Thanks. I tried his method. Had you solved it with this method ?
( I wrote a PM to Burgo)

Well it's taken me a while but I've finally completed video solutions for all the pentahedron planets, and the standard 3 layer and 5 layer.

There seems to have been not much interest in these crazy pentahedrons. Perhaps everyone's over crazy.

Anyway, I still wanted to let people know that I'd made them. Saturn and neptune follow a corners last approach. The other planets have two different tutorials each for most of them: a corners last approach, and an edges last approach. I'm particularly happy with the edges last videos because they only use [1,1] commutators to do the job. I find the solves more interesting as well. In the edges last approach, I reduce corners etc using simple turns and then deal with the edges using things like [LULU'] x 5. Peronally, I like it better than using the corner 3-cycles. But those corner 3-cycles are still there on the corners last methods.

Anyway, if anyone wants to take a look, or tell someone they know about them, here are the links, both for my blogger site (which have the full tutorials with text also) and also youtube playlists (which are just the videos).

Thanks, Rline for this terrific series. It looks like it was a huge undertaking and is a most impressive piece of puzzle analysis.

Maybe some day you could post how you go about analysing new puzzles to find solutions. I have the crazy cubes on their way and have solved Jupiter using existing known techniques. But I doubt that what I know already will solve the rest. I would like to solve them myself but really don't know how to start analysing new ones.

Once again thanks for a great resource, I have enjoyed it immensely and may get a few of the pents in the future.

Hi Crazy Puzzlers.



I knock on the door of this club.


I solved the Crazy Tet Uranus. Perhaps it was an accident.

My solution is little bit different to Burgo's solution. It's very difficult. I put the solution as PDF file attachment. Perhaps someone understand this.

Solving outer edges, inner edges and corners are relative easy.
In my solution the last step is solving the circle corners. In the PDF there is a shematic painting of permutate the triangles with a sequence.

Much terrible fun with this.



Cheers,

Andrea

Hi friends,

Solving the Crazy Tetrahedron Uranus:

I added the notation to the textfile. The key is this permutation.
A 5 cycle:

R U L U‘ R‘ U‘
R U L U‘ R‘ U
R U L’ U‘ R‘ U
R U L’ U‘ R‘ U‘

Each circle is a circle - corner. Look from top to the tip of tetrahedron.
If you turn the sequence you must turn the orange face to the top.
The picture shows where the triangles go.
piece 1 goes to piece 2 , piece 2 goes to piece 3 .... piece 5 goes to piece 1


I added this to the

PDF.

Cheers,
Andrea

Andrea, congratulations! This is incredibly impressive. I'd say Welcome to the Club, but I'm nowhere near it.

Great work!

Hi friends,

Solving the edges and outer corners is not the difficult part.
The difficult part are the circlecorners (cc). If the tet stand on table and you look from to to the cc's you get the picture in the last posting.
I put paper on the cc's to follow the permutations.
You can divide the cc's in two groups. First step, don't look to the tip-cc.
Then you get two groups.
You can solve the group "B" with the mirrored sequence.

The permutation 5->1->2 thows that all pieces of one group are changed. In the step before the last sequence 2 pieces of one group are wrong and two pieces of tip are visual changed.
The last picture in the PDF ( screenshot from BO HU simulator) looks like a 3 cycle, but it is a 5 cycle , too.

I gues that you must only make the sequence
R U L U‘ R‘ U‘
R U L U‘ R‘ U
R U L’ U‘ R‘ U
R U L’ U‘ R‘ U‘ and inverse

3 or 4 times for each group to solve all circle corners. I had 4-5 solves of Crazy Tet Uranus.



Cheers,
Andrea

Congratulations Andrea,

I have enjoyed looking over your Uranus Tet method, I particularly liked your inner edge 3cycle. I had a look at what you were doing with the CCs and I found a pure 3cycle, albeit a very long one:
[LUB>LD>BUR]
RUL'U'R'U D L'U'RULU' y
L'U'RULU' D' RUL'U'R'
URULU'R' D UL'U'R'ULU y'
L'U'R'UL D' U'RULU'R'U'

Interesting that you solved the corners first and I solved them last.
Cheers,
Burgo.

Hi Burgo,
thank you for sharing your 3 cycle sequence. Perhaps this is easier to memorize the 3 cycle than a 5 cycle but the sequence is hard to memorize.
I use only my last sequence. The 5 cycle I begin with 5 > 1 > 2 >3 >4
, it's memorizable as a spiral around the tet beginning in one group and ending with the two tip-corner circles. Perhaps this is an easy method to memorize this. Now we have two methods. I don't like solve a puzzle looking to paper. So, I memorized the permutations and sequences.
Do you solve the tet without look on paper ?

Cheers,
Andrea

Hi friends from crazy planet,

thank you Burgo for the response to my solution.

I made a litle video obout solving. It's without sound. It's not a tutorial. because my tutorials are to bad.

I hope no-one is upset by me resurrecting this topic!

Recently Rline showed on his YouTube channel how to make the whole set of Crazy pentahedra from just one of the set and the set of Crazy tetrahedra from 2 in the series. This stimulated me into a purchase and I've started on the pentahedra. I started with the standard 3 layer and was lulled into a false sense of security as it was tremendously simple to solve - took me less than 2 minutes.

I then moved to the Mercury pentahedron and after a weekend, am getting nowhere by myself!

I now have a scrambled puzzle which I find impossible to check algorithms on. So how do you guys go about this? I will need to keep disassembling my puzzle each time to check a possible algorithm! This is really not feasible!

Is it essential to use a simulator when trying a new puzzle?

I don't have access to a Windows machine so will struggle - I think Andrea's simulator (YAPS) is the only one which does these circle pents & tets and it is a windows executable. Does anyone have any suggestions on how I can progress?
Can I do it on a puzzle?
Or must I get hold o a Windows box for this purpose?

Thanks!

I ordered them too thanks to his videos! I'm still waiting for mine to arrive though.

Hi Kevin.
My java program cube1.2 work on every operating system, but it simulates only crazy cubes.
The YAPS program simulates crazy cubes and crazy pentahedron.
It's posssible to compile the sources on every os, if QT library is avaiable.

Download the yaps-src.zip and compile it. I tested it under linux. Perhaps it's possible to compile it with a mac.

Cheers,
Andrea

Thanks Andrea,

I think the QT library is available on all macs but I don't know how to compile your source code on the Mac. I think I need to be part of the developer program ($99) to be able to compile the programme.

I wonder whether it will work under WINE.

Do you plan on redoing YAPS in Java?

Hi Kevin,



In past,many years ago, i owned a mac mini. It was possible to install X Code and compile source code, without paying $99 for de developer. It's not necessary.



Perhaps in far future. But not in moment.
Yaps shows puzzles schematic. My Cube1.2 java program uses an own graphics engine, this works only with planar faces.
Some puzzles need spherical faces, ( example: rex cube, bauhinia, pentahedron).
Programming is very much work.
Do you find other simulators ? By example Bu Ho's circle puzzle ?

Bo Hu did make a simulator for the Crazy pentahedra puzzles. And it does support all the variations, I believe. But I haven't made an English webpage and clean up the code to make it work with Chrome and Firefox. There are always some inconsistency in his webpage (javascript code). So it works on IE but not on Chrome and Firefox.

I look forward to when you have time to do it Schuma!

No one has yet said whether they consider it necessary to use a simulator to work out how to solve these.
Do you think I can solve this series (bear in mind that I'm not very bright! ) with only a puzzle to practice on or is a simulator required?

Your opinions are always important!

You don't need a simulator to solve things Kevin, but it does make life easier, then the question is.. what do you believe is the challenge of the puzzle? Instead, let me ask you.. Do you ask for all of your wooden assembly puzzles to be sent assembled or disassembled?

Cheers,
Burgo .
