Whgen engaged on a task, I like to mark my progress in fractions, and was musing yesterday about how frustrating for such a purpose are even numbers divisible only by 1, themselves, 2, and half of themselves. Such numbers (the one that raised my ire yesterday happened to be 26) deserve a special epithet, since as Dr. Bill never misses an opportunity to insist, there should be a single word for every phenomenon possible. So, is there a word for such wannabe primes?
