Talk:Narcissistic number

From Wikipedia, the free encyclopedia

• These examples shouldn't have links, since they are base 3 and 4 numbers but the links are to base 10 numbers and so are meaningless --206.171.6.11 15:12, 8 November 2006 (UTC)
  • Some base three Armstrong numbers are: 0,1,2,12,122
  • Some base four Armstrong numbers are: 0,1,2,3,313

[edit] Open question?

The article says:

However, it is not known if the only base 10 numbers equal to the sum of the cubes of their digits are 1, 153, 370, 371, and 407.

Surely this is untrue? The sum of the cubes of the digits of n cannot exceed 9³·log(n). But this quantity is far smaller than n when n is bigger than, say, 10^{6. And a simple brute-force search should take care of all smaller numbers. -- Dominus 21:05, 31 January 2007 (UTC)}

^{In fact, it is untrue. The comment at [1] says essentially the same thing. I have removed the mistaken assertion from the article. -- Dominus 21:12, 31 January 2007 (UTC)}
