The algorithms are just working algorithms and are probably too long. Can anybody apply Kociemba's algorithm to those positions? The patterns form a small portion of a very large collection of pretty patterns found by Mirek Goljan and Peter Nanasy from Czech Republic. The algorithms below are the awkward "outliers" for which we were unable to find a reasonably short "logical" algorithm. It looks like Kociemba's algorithm is the only chance. Thanks in advance for your help! Jiri Fridrich P.S.: Visit my speed cubing page at http://ssie.binghamton.edu/~jirif. The complete collection of pretty patterns will be there soon.
