Perhaps this is why it was selected? 7, > 11, and 13 all numbers associated with luck? Well, I was just pointing out that the repeating decimal was simply an artifact of the number we chose. As for 360, it's just co-incidence that those primes don't divide (and note that other primes - 2, 3, 5 - do divide), it was chosen for it's large number of evenly divisible numbers - 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, (16), 18, 20, and so one (16 is a terminating decimal - 22.5). -- "It has occured to me more than once that holy boredom is good and sufficient reason for the invention of free will." - "Lord Leto II" (Dune Chronicles, by Frank Herbert) http://members.tripod.com/~Nik_Taylor/X-Files/ ICQ #: 18656696 AOL screen-name: NikTailor
