%N Number of integer partitions of n that are empty, have smallest part not dividing all the others, or greatest part not divisible by all the others.
%C First differs from A343345 at a(14) = 80, A343345(14) = 79.
%C Alternative name: Number of integer partitions of n with either no part dividing, or no part divisible by all the others.
