A119268 Number of infinite-dimensional partitions of n up to conjugacy. 9

%I

%S 1,1,1,2,4,7,14,28,58,120,260,571,1296,2998,7124

%N Number of infinite-dimensional partitions of n up to conjugacy.

%C Partitions are considered as generalized Ferrers diagrams; any permutation of the axes produces a conjugate. An infinite-dimensional partition thus has infinitely many conjugates. However, an infinite-dimensional partition of n always has a conjugate of dimension at most n-2, so this sequence is always finite.

%Y Cf. A119338, A118364, A118365.
