- Apr 1, 2007I don't know anyone knows a 25 turn HTM scramble (without obvious cancellations) that result in the solved state again, but I do remember a challenge a year or more old that had a 13 moves one (if memory serves me correct) as a winner. I thought Stefan found it. There were also some longer ones naturally. I am not going to try to find a 25 moves one, but I think that if you search for that thread, you will see that one is extremely likely to exist.

Intuitively this must be the case, and I think it's a assertion that
everybody here is willing to believe. But this is much easier than
proving the other things being discussed, all this takes is finding a
single case. I wouldn't even call it a "proof," just a "example/counter-
Just entertain me and see if anyone here can find a 25 turn HTM
scramble that produces the identity/solved state. I'm having a hard
time finding one. Oh and by "scramble," I am discounting the really
trivial cancellations and such.
