Description

Maybe degreeLength should also give an error below.


i10 : R = ZZ/101;

i11 : degreeLength R

o11 = 0

i12 : degreesMonoid R
stdio:12:1:(3): error: no degreesMonoid for this ring

Research direction

Reproduce the Macaulay2 transcript using degreeLength and degreesMonoid on ZZ/101, then locate the implementations or entry points for both operations. Compare their handling of rings without degree structures. Done means degreeLength reports an appropriate error for this ring, consistently with degreesMonoid.
