Friday puzzle -- short anagrams
Alex Y
Find four three-letter words that are mutual anagrams (i.e. all four words are rearrangements of the same letters). All four must be legitimate English words, not abbreviations or initializations.
I was able to find one such set, and have seen one other. As might be expected, in each set there were words familiar to any reader of Dick and Jane as well as words not part of your every-day usage.
It might be interesting if one of the computer guys here tested all possibilities to see if there are more than two such sets.
