That's indeed an intersting solution!

I found another small improvement for the Giftwrapped Cube (Order 3).I simply replaced the corner twisting start with CU2 WU B WU2 F2 WR2 F WU L WF2 L2 WU2 R Then 2 turns cancelled ... Per

I was working quite some time on this pattern for the 4x4x4 cube. My current approach requires 78 moves to build a nice Double Python: Double PythonR U' (WR2 B' WR F2 B WR F2) U R' SD2 (TD MB2 TD' TR2 MD' TR2 (MU TF2 MU' TB2)2) SD2 U (WR2 U2 MR2 TU2 MR2 MU2 ML2) (D (WR WF' WR' WF) D') U' MF' D2 MF WD MF' D2 MF WD' MB D2 MB' WD MB D2 MB' WD' MU' MR' MU L' MU' MR MU R F MD TF' R' MU R TF MD' F' R' MU' L (78 btm) P.S. If someone likes to fill in the centers, here is an algorithm that just does the edges: Double Python (Edges Only)D MF' D F D' MF D F' U D2 ML' U L U' MR2 ML U L' U' MR2 SU' R' D' MR D R D' MR' MF2 U2 MB' U2 MB L2 MF' L2 U2 MF' U2 MF' (40 btm)

@ Walter I tried a number of ways to lower the move count of the Single Ring and Nested Rings algorithms, but found none shorter than 20 and 30 moves, respectively. So, I guess that they are probably not that far from optimum, unless Per could find a breakthrough... For centers of the Double Python pattern, I will simply wait for a solution from Per and try to optimize it afterwards

Here is a possible explanation:
The order of Part 1 is 4, whereas that of Part 2 is 2, so the order of Part 1 + Part 2 is 4.
Executing the alg of Part 1 two times solves centers but not edges. Edges of Part 1 need to be executed 4 times to be fully solved.
This solution is not as 'clean' as yours, btw...

This solution is not as 'clean' as yours, btw... Well OK. But add (some) physical turns to your sequence and it becomes a sequence of order2. So essentially it has order 2 anyway Per

The Rings (Order 2) actually looks nicer on the 6x6x6 cube. But then it takes 16 turns. Foe some strange reason the applet shows 17 block turns. This is a bizzarre bug. I inserted 7 turns into 9 turns. How can that become 17??? Edit: The error lies within this sequence: N3R2 T2B2 N3R2 T3B2 N3L2 N3B2 M2R2  counted as 8 turns in the applet. This requires some investigation I found the culprit. T2B2 is counted as 2 block turns. T3B2 is correctly counted as 1. The error is the same on any size cube, from 3 and up to 7. Fix ASAP please !!!! Per

I already noticed this bug yesterday when I analyzed your 'Rings (Order 2)' algorithm. This algorithm is actually a 14mover and not a 15mover. In the current applet version T2B2 is counted as 2 block moves instead of 1 move. This was caused due to an incorrect entry in the notation file and also because of a problem concerning repetitive moves in special cases. This bug has been corrected right away. Since we had to lay hand on a very sensitive part of the parser, we like to run some more tests before releasing a bug fix. We will update the applets and CubeTwister as soon as possible. The move T2B2 is actually an alternative tolken which is accepted along with the shorter TB2. Both tokens stand for the same move, but TB2 compared to T2B2 is counted correctly. So, as a workaround you can use TB2 instead to get correct move counts.

I took the idea from the block 4flip further. First i modified the start and got T3F2 N2R N2L T3F2 N2R2 N2L2 Then i commuted that with D SR2 D to get a "8flip". T3F2 N2R N2L T3F2 N2R2 N2L2 D SR2 D N2R2 N2L2 T3F2 N2R N2L T3F2 D SR2 D Then conjugated with F to get a sequence that could be repeated 3 times around the cube. Superflip on small edges.I guess shorter is still possible ... Actually it can be brute forced. Start with SL F R B U L2 U B L R2 U2 F2 U and commute with N2R2 N2L2 N2F2 N2B2 N2U2 N2D2. Superflip on small edges.I still find the first solution cuter and more "pure" Per

Some previous algorithms have been slightly improved : Patched Rings (30 moves)R L B2 (U' D' MF2 SD' MB2 ML2 MB2 D2) B2 L' R' TR [U, TF' MD2 TF] TR' TR [F' MU2 F, TD] TR' Patched Rings4 Small Flips (Version 1) (11 moves)NU SL U2 SL' NU ND SL U2 SL' ND' NU2 4 Small Flips (Version 1)4 Small Flips (Version 2) (13 moves)F2 ND SL U2 SL' NU ND SL U2 SL' ND2 NU' F2 4 Small Flips (Version 2)By adding permuted centers to flipped edges, we got (yet unoptimized) deep flips: 4 Deep Flips (Version 1) (23 moves)NU SL U2 SL' NU ND SL U2 SL' ND' NU2 B2 (L2 NU' NR2 NU TR2 L2 NU NR2 NU' TR2) B2 4 deep flips (version 1)4 Deep Flips (Version 2) (24 moves)F2 ND SL U2 SL' NU ND SL U2 SL' ND2 NU' F2 NF2 (L2 NU NR2 NU' TR2 L2 NU' NR2 NU TR2) NF2 4 deep flips (version 2)2 Deep Flips (26 moves)ND2 F2 NU' F2 NU L2 ND' L2 F2 ND' F2 ND' NL NF' NL' F' NL NF D NL' NU NL D' NL' NU' F 2 deep flips

@ AndrÃ© (a.k.a. glazik) The bug has been fixed in the current version of CubeTwister 2.0alpha144. perfredlund wrote: For some reason i could not paste proper notation into the URL's ... Parser could not handle it!! I guess the TwistyPuzzles.com editor doesn't like Left and Right Square Bracket characters within tags like 'URL'. But it may work if you replace these characters with the corresponding URL Encodings. In this case %5B stands for the Left Square Bracket and %5D for the Right Square Bracket: 4 Small Flips (Version 1)[R' F D' R F', NU2 ND2] (14 btm) 4 Small Flips (Version 2)[R' F D' R F', NU ND'] (14 btm)

I honestly thought the 2 deep flips was well known from speedsolving bigger cubes. This sequence is only 12 block turns Per

This commutator gives you easily both versions of 4 deep flips: [T2R N2D T2R2 N2D2 T2R2 N2D T2R,T2U2] Per

I got inspired to make a rings pattern. I started off with the following: L D L D U2 L D2 B2 D U2 L D L R2 D L2 F2 R2 It twists all but 1 corner clockwise. I reversed it with double layer turns to achieve 8 rings. 1 of the rings needed adjustment to also be clockwise: R F R T2L U2 T2L N2U T2L U2 T2L N2U R F R 8 small clockwise rings.I guess must be near optimal (49 turns).

I managed to squeeze out 2 more moves from your '8 Small Clockwise Rings'. BTW, this pattern also looks nice on a 5x5x5: 8 Small Clockwise RingsU R2 U2 L' (U L2)2 WF2 L' U' WR2 WF2 (D L')2 (TL TD')2 MF2 MR2 TU TL MF2 (TL2 TU')2 TL TU2 TR2 TU' B L' B' (TF' D2 TF ND TF' D2 TF ND') B L B' (48 btm or 47 btm actually)
