%N Heinz numbers of integer partitions that are not totally nondecreasing.

%C The first term of this sequence that is absent from A112769 is 150.

%C An integer partition is totally nondecreasing if either it is empty or a singleton or its multiplicities (where if x < y the multiplicity of x is counted prior to the multiplicity of y) are weakly increasing and, taken in reverse order, are themselves a totally nondecreasing integer partition.

%e 150 is the Heinz number of (3,3,2,1), with multiplicities (1,1,2), which has multiplicities (2,1), which are decreasing, so 150 does not belong to the sequence.

%Y Complement of A316529.

%Y Cf. A056239, A071365, A112769, A181819, A182850, A242031, A296150, A305733, A316496, A317258.
