• Philip Osterlund, while a grad student at Univ. Minn., wrote the GAP (version 3) package Abstab.g which could be used to help solve the Rubik's cube (and other permutation puzzles). According to Alexander Hulpke: "AbStab has not been ported to GAP4. However (as of GAP4.4) the code for expressing elements as words in generators has substantially improved, utilizing methods similar to AbStab. (e.g. for Rubik's Cube I obtain length ~100 words). I am not aware of any general approach (i.e. not tuned to Rubik's cube) that does essentially better." See section 5 of chapter 37 of the GAP reference manual for information on GAP commands related to this.
• SAGE has several (free and open source) cubsolvers included with it. SAGE is a cross-platform (free and open source) math software program. Examples are given in the Reference manual in the Rubik's cube section.
