These files contain equivalence classes of words in the free group on two generators, where two words are equivalent if there is an automorphism that maps one to the other.
They were computed with my package EquivalentWords.
The generators are *a* and *b*, and their inverses are denoted *A* and *B*.
The words listed are limited to those that are both minimal with respect to length in each class and lexicographically first among all their cycles and all permutations of generators.
The root classes are special automorphic conjugacy classes.
See my first and second papers with Bobbe Cooper for more information.
