A while ago I noticed that the letters 'e', 't', and 'a' can be arranged to form four 3-letter words: tea, eta, ate, and eat (tae may count). I also noticed that the letters 's', 't', 'o', and 'p' can be arranged to form stop, pots, opts, spot, and tops. I was wondering if any of you could discover any similar three-letter or four-letter combinations.
