##  Hecke - symmcomb.gd : Combinatorial functions on partitions.     ##
##                                                                   ##
##     This file contains most of the combinatorial functions used   ##
##     by Hecke. Most are standard operations on Young diagrams or   ##
##     partitions.                                                   ##
##                                                                   ##
##     These programs, and the enclosed libraries, are distributed   ##
##     under the usual licensing agreements and conditions of GAP.   ##
