Hello all,

This is my first post here and as for the time being I’ve been happy to only read the digests of some of the conversations here. Then inspired by your info about the shortest algorithms I started to find out good ones again and found actually a 12 move 4-color piece 3-cycle. Then I thought it would be of interest to share it with you.

So here is the algorithm in log file notation:
48,1,1 101,-1,1 185,1,1 101,1,1 48,-1,1 129,-1,1 48,1,1 101,-1,1 185,-1,1 101,1,1
48,-1,1 129,1,1

My main idea was to look for a way to replace one 4-color piece in one side with 5 moves and then commute this algorithm with moving this side. The solution finally came by a bit of accident but anyway here it is.
