|  |  D.15.10.5 LRcoprod Procedure from librarylrcalc.lib(see  lrcalc_lib).
 
Example:Usage:
LRcoprod(z); z list of integers (partition)
Return:
list of lists
Purpose:
computes the pairs of partitions x and y for which
the Littlewood-Richardson coefficient c^z_{x,y} is non-zero
together with that coefficient
 
Note:

// coefficient c^z_{x,y} is non-zero together with that coefficient
// for z= (3, 2, 1)
list z = 3, 2, 1;
