Description
See the code below:
restart
R = ZZ[i]/(i^2+1)
I = ideal"5,i+2"
mingens I
-- returns | 5 i+2 |
minimalPresentation I
-- returns ideal (5, 5)
This shouldn't happen since the ring of Gaussian integers is a PID, but I'm assuming it's happening because i+2 is not homogeneous.

Research direction
Reproduce the Gaussian-integer example using mingens and minimalPresentation, then inspect the entry points for how each handles the nonhomogeneous generator i+2. Determine the intended result for this PID case and add regression coverage showing that the two operations handle the ideal consistently.
