Robert Israel: Can you give an example with 5 roots for n = 14, 15 or 16? My Maple program only gets 4.

Robert Israel: The first appearance of 5 roots I get is at n = 19, with x^19+x^18+x^16+x^11+x^9+x^6+x^5+x^4+x^2+x.

Robert Israel: So my program gets 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5. Can anyone confirm?
