Super-supercube challenge!!

You must still be misinterpreting, I've tried this sequence on CubixPlayer and it says it's SuperSolved. The corners of the 5x5 should never move.

Hmmm. That is weird. Well here is my notation. On the 5x5x5 we have layers R r M l L going from left to right. From top to bottom we have U u E d D. From front to back we have F f S b B. M turns same way as L. E same way as D and S same way as F. With this notation my complete and improved solution is:

1. l' u' (l m) d' (l'M') u' (l M) d (l' M') u2 l (11 turns block turn metric)

2. f l (f' S')d (f S) l (f' S') d' (f S) l2 f' (11 turns)

A full explanation will follow shortly. Part 1. and 2. are 2 block 3-cycles.

I don't see why you consider it necessary to write 3x3 algs in 5x5 notation, but here you go:

u r' f2 r (S' b) r' f2 r (S b') u'
d' l b2 l' (S' f') l b2 l' (S f) d

I don't see why you consider it necessary to write 3x3 algs in 5x5 notation, ...

A matter of taste i guess. I always do the alg on a 5x5x5 to verify lack of side effect

Sometimes easily solutions are buried in bad notation. I had the same 20 turn solution all the time. But i had written my block cycles with solely outer turns (on 3x3x3). Changing to proper commutator turns (with block turns in this case) was the way to go(to avoid side effects).

Coincidentally there is at least 18 different 20 turn solutions. 3 ways to cycle first 3 blocks. Then 3 ways for the last 3. In addition there are 2 ways to split it into 6 blocks ...

Your solution is 22 moves - you used two setups, I used one. But yeah, a 20 move solution is probably the way to go.

What i meant is that my normal cube in cube is a 20 turn solution, involving 2 block 3-cycles. I realised i should "normalise" that one right after i posted my 22-turn solution. Oh well, you beat me to it cause of my "stupidity":tu
