- I don't know much about this news-group, but I thought
- that I might post this list of number-theoretic numbers.
-
- Let N be an n-digit number which is separated into it's
- decimal digits, raise each digit to the nth power and sum
- them. Let N be a unique number if the sum is equal to N.
-
- 28116440335967 --> The singular 14 digit number I've found!
- --> Strangely there are no 12 or 13 digit numbers with
- this property. This is a certainty.
- 32164049650 --> 11 digit numbers are abundant.

- 912985153 but none of these are new.
