In the August 1989 Word Ways, Dmitri Borgmann's article "The ACEINORST Transposal Problem" brought the total number of transposals based on the letters ACEINORST to 55. Dmitri' article queried the extent of the transposability of the letters AEILNORST. In my article "The AEILNORST Problem" in the November 1989 Word Ways, I offered a total of 24 transposals using those nine letters. My article finished by suggesting that a very slightly different set of nine letters, AEIMNORST, was another fecund group.
