A powerful s.o.d. (Posted on 2012-08-14) Difficulty: 2 of 5
There are three six-digit numbers such that each is a 4th power of its sum of digits .

1. List them.
2. Each one has a certain peculiarity (or more than one). Try to define it.
3. Ignoring the 6-digits constraint , how many integers like that exist?
