Talk:Prime numbers
From TheTangentSpace
Congratulations Tyler! Your "an odd number is prime iff it can't be represented as the sum of an odd number of consecutive odd numbers" is a gem. Is it new? A search of the web hasn't found its like yet. Can anyone help here?
Hope to be able to add some connections to sieves in the near future.

originality
Thanks, djw!
As you emailed me, someone has at least found a very similar result before.
In general, results like this that involve only elementary methods with short proofs are very rarely original. So I'm not really surprised. But it is still a "cute" fact and perhaps there are still interesting and new ways to extend or use similar ideas to this.
