Packing Centrosymmetric Patterns of n Nonattacking Queens on an n × n Board

摘要

SQ(n) is the maximum number of patterns that can sit on the n × n board where each pattern consists of n nonattacking Queens placed symmetrically around the center. Each square of the board has at most one Queen. Q(n) is the same except that "placed symmetrically around the center" is not required.
