an anagram of a word is obtained by permuting its letters.

a-how many anagrams does the word "MAIRE" have
b-Same question for the word "OISEAU"

1 answer

if all you want is permutations of the letters,
MAIRE: 5! = 120
OISEAU: 6! = 720

If you want your anagrams to be actual words, then of course there will be a lot fewer. Better get a good French dictionary.
