socleDegrees -- lists the degrees of the socle generators

Synopsis

Description

L is the list of socle degrees of M, with multiplicities. Thus L = {} if the socle is 0.

i1 : R = ZZ/101[x,y,z]

o1 = R

o1 : PolynomialRing
i2 : M0 = R^1/(ideal(x,y,z)*ideal (x,y));
i3 : M1 = coker random(R^{1,2}, R^{0,-1,-2}); -- dim 1
i4 : M2 = coker random(R^{1,2}, R^{0,-1,-2,-4}); -- dim 0
