%N Partial sums of A036983.

%C Partial sums of number of invariants in Hilbert basis for binary forms of degree n. Extending this is related to a "gorgeous open question of great antiquity" [J. Towber, 19999]. The subsequence of primes in this partial sum begins: 2, 13, 43.

%F a(n) = SUM[i=2..n] A036983(i).

%e a(9) = 0 + 1 + 1 + 2 + 4 + 5 + 30 + 9 = 52.

%Y Cf. A036983, A036984.
