Hi,
some might have recognized that I am quite obsessed with
1. collecting and/or making all variants of a specific series.
2. bandaged cubes.
After I had built my first two dozens bandaged cubes I wondered how many bandaged 3x3x3 are there.
Here is one results of all that:
I don't want to make further explanations since this is also a test of its self-explainability (?).

To Bram:
You might not remember it, but 5 years ago you asked me how many variants for the 3x3x3 are really interesting. I think that I can answer that now: 5705 out of 7356

EDIT: Uploaded a new version to a new thread:

I have all 3 of your bandaged programs Andreas. Skewb, Pyraminx and 3x3. I play with them all the time, and still haven't solved the "hardest bandaged cube." among the several I've built. You know which one I mean.

This program is great! Thanks.
ANy update on that 4x4 program? :D

But how many of those 5705 can you solve? :-)

There are also bandaged pucks, and bandaged 2-layer pucks...

That is a LOT of bandaged puzzles. I actualy have the D2800001c240031 megaminx sitting on my desk right now. I copied the bandages of a Rotascope sliding puzzle that I thought looked nice: http://www.jaapsch.net/puzzles/rotascope.htm.

I am not much of a solver, but it is one of the hardest puzzles I have ever tried (emphasis on tried not solved :lol:).

I am afraid I don't know.
With "hardest bandaged cube" you mean this one?

You can delete that old rubbish. You might have noticed that Skewb and Pyraminx and more are now integrated into one program.

Regarding the 4x4x4:
The calculation program for the 3x3x3 needs 3 minutes for 2^54 variants.
The calculation program for the 3x3x3 with bridges needs 13 hours for 2^81 variants.
The calculation program for the 4x4x4 would need to crunch its way to 2^108 variants. Guess what I did.

I can (or could at a time) solve the ones moved to the right list.
Bandaged pucks are interesting but after analyzing the dodecagonal prism I decided to analyze the Skewbic Dodecahedron first.

Great minds think alike:

Although this one was inspired by Mefferts bandaged cube, the solution for the last pieces should be similar:
I have lost my notes after 2 moves, but I know there is a sequence with length=7 involving only the three shown sides. This sequence permutes only 5 of the corner-edge-blocks.


Some constructive criticisms for the program anybody?
I hope nobody without appropriate region setting sees any german.
