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?

What about part 2(applies to Charlie as well) and 3(only you.)?
