Talk:Self number
From Wikipedia, the free encyclopedia
Any applications? - Highwind
- Probably not. But mathematicians and number aficionados are very interested in them just the same. PrimeFan 22:50, 6 Aug 2004 (UTC)

[edit] Colombian and Columbian numbers
I'm embarrassed about this, but I have to admit it. For the first draft of this article, I wrote "self number or Colombian number," where I should have written "self number or Columbian number." That's the spelling given both by Mathworld and the OEIS. It's an alternate term, but there is still a lot of older literature that uses it, so I apologize for screwing it up.

[edit] k
What does the k stand for in the formula? --Shandris 07:11, 16 May 2006 (UTC)
- I think it's just a convenient running variable. m might be just as suitable. The reason n is not used is that it would lead one to expect that the recurrence relation gives all self numbers, when in fact it just gives an incomplete though infinite list. PrimeFan 15:57, 17 May 2006 (UTC)
