Long time ago I've seen a book on group theory and there was an appendix about rubik cube. I remember there were only three steps that enabled me to solve my cube (three strings with letters encoding some rotation). I don't remember them now and I can't google something similar either (I find only very long and complicated solutions). Can somebody tell me what those steps may have been?
EDIT: Maybe this helps: I've remembered that first subroutine involved swapping edges to make crosses on each side, and the last (the longest) is rotating three corners on front side. The second was about rotating colors on corners in place or something like that.
