I don't have a formal reference for you, but this seems intuitively correct to
me: put the strings in a canonical form so that all equivalent strings reduce
to the same string, then hash conventionally. Eg., for rotation, the
canonical form of a string is the rotation which gives the smallest value when
the string is considered a binary number. In other words, alphabetize all the
rotations and then take the first one.
