- Defn: A pretty wild narcissistic number is:
- ... an integer n that can be expressed using just the digits of n (each digit used once only and in order from left to right) and the operators + – × ÷ ^ √ !
Such numbers are said to pwn (pronounced: own). I allow for non-trivial concatenation of digits (e.g. 360 = 3! × 60), though such cases are quite rare.
The 2-digit numbers that pwn
24 = (2 )! , , (2 + )!
36 = 3! 6 (a square triangular number)
71 = (this num really pwns – 'tis also prime and a Brown number)
