Jotto Fact OTD

My perl programming in Jotto-space is yielding all sorts of interesting fringe information. Today's obsession is anagrams. Are you curious to know how many 5-letter words have an anagram? I'm curious to know what you'd expect! So let's trade info. (Note: I've made the scale extend the entire length -- no multiple-choice help here!)

Note: only words with an anagram that also appears *in the 3252-word dictionary* count for the purposes of this poll.
