Synopsis

Description

Returns the width of an element of a free OI-module.

i1 : P = makePolynomialOIAlgebra(2, x, QQ);
i2 : F = makeFreeOIModule(e, {1,1,2}, P);
i3 : installGeneratorsInWidth(F, 4);
i4 : f = x_(2,4)*e_(4,{3},1)+x_(1,3)^2*e_(4,{2,4},3)

                     2
o4 = x   e        + x   e
