You seem back-to-front, Jon.

8 is composite, 17 is prime and {1,2,3,4,5} was provided as a solution.
Therefore the condition that the pair's elements are distinct _was_ a
condition in the first one?
If it wasn't a condition, then {1,2,3,4,5} wouldn't have been a solution.

Nope, trees and forests with loops are frowned upon (and any other DAGs, of
course)
