%N Third Moebius transform of A000219. Number of plane partitions of n whose multiset of rows is aperiodic and whose multiset of columns is also aperiodic and whose parts are relatively prime.
%C A multiset is aperiodic if its multiplicities are relatively prime.

%F The Moebius transform T of a sequence q is T(q)(n) = Sum_{d|n} mu(n/d) * q(d) where mu = A008683. The first Moebius transform of A000219 is A300275 and the second is A323584.
%e The a(4) = 7 plane partitions with aperiodic multisets of rows and columns and relatively prime parts:
