at a well-attended brunch on saturday, i asked everyone at the table what an irregular prime number is (i know that the first irregular prime is 37, but i don't know why).
here's a link to the wiki article on the subject. i can't figure out what the fuck they're talking about. can anyone out there explain this to me in plain english?
some context: i asked about this, because i am teaching an excerpt from ralph ellison's
invisible man at the moment--specifically the prologue and the first chapter (which is often anthologized as a stand-alone short story called "battle royal"). in the prologue, the narrator mentions
twice that he has exactly 1369 lightbulbs in the "hole" he lives in. i was curious about the number, so i did some quick factoring and figured out that it is the square of 37; and that its only factors are 1, 37, and itself. i
wiki'ed the number 37, and that's where i found out that it's the first irregular prime.
