%N Number of sublattices of the divisor lattice of divisors of n that include n.
%C A divisor lattice is closed under GCD and LCM. First differences of A074986. Depends only on the prime signature of n.
%F a(A002110(n)) = A326878(n).  _Andrew Howroyd_, Apr 17 2020
%e The a(6) = 7 sublattices of {1,2,3,6} that include 6 are: {6}, {1,6}, {2,6}, {3,6}, {1,2,6}, {1,3,6}, {1,2,3,6}.
%Y Cf. A051839, A074986, A122978, A122979, A122980, A326878.
