A self-conjugate partition is a partition whose conjugate partition is equivalent to itself.
The Ferrers diagrams corresponding to the self-conjugate
partitions for
are illustrated above. The numbers of self-conjugate partitions of
, 2, ... are 1, 0, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4,
5, 5, 5, 6, 7, ... (OEIS A000700).
The number of self-conjugate partitions of
