The theoretical maximum is 325 words from 5 different letters: 120 five-letter words, 120 four-letter words, 60 three-letter words, 20 two-letter words, 5 one-letter words (including acronyms) made by listing the letters in every possible order (abcde, abced, ..., edcba and ending with a, b, c, d, e). For most sets of 5 letters, the number is a fraction of that, from 20 to 40 words.
