# Brilli the Fortune Teller

Brilli the ant states that "Given any set of 30 distinct integers from 1 to 50 (inclusive), there must exist 2 integers whose absolute difference is exactly $$N$$."

What is the sum of all possible values of $$N$$ in which the statement is always true?

Details and assumptions

You may use the fact that $$\frac{30 \times 29} {2} = 435$$.
