In Transposing Rates (WW87195), Jeff Grant listed the 24 transpositions of the four letters AEST. He said "Although some of the terms and references are rather obscure, it is an accomplishment unlikely to be equalled with any other set of four letters". This is a challenge which appears to have lain dormant for 20 years. Here, I offer other sets of 24 transpositions.
