%N a(n) = number of strict partition numbers >1 that are proper divisors of the n-th strict partition number.
%C Let p(n) = number of strict partitions of n. Then p(11) = 12, which is divisible by these 6 strict partition numbers: p(2) = 1, p(3) = 2, p(5) = 3, p(6) = 4, p(8) = 6, and p(11) = 12; discounting 1 and 12 leaves a(11) = 4 divisors.
%F a(n) = A332888(n) - 2 for n >= 3.
