  1. Yes, it turns out that the answer is Googlable... I like to call these "factorially self-referential" numbers, in that they refer to their own prime factors: 14 = 1st prime x 4th prime 154 = 1st prime x 5th prime x 4th prime 1196 = 1st x 1st x 9th x 6th 2127 = 2nd x 127th 61411 = 61st x 4th x 11th 66079 = 6th x 6th x 7th x 9th 172482 = 1st x 7th x 24th x 8th x 2nd 223227 = 2nd x 232nd x 2nd x 7th 279174 = 2nd x 7th x 9th x 1st x 7th x 4th 291318 = 2nd x 9th x 1st x 318th I think this is it for integers below 1 million. Perhaps others will want to look for more -- or just let this bit of silliness stop...
  2. 14, 154, and 1196 all have a remarkable characteristic--one that no other integer below 2000 has. What is this characteristic?
