Comment (by stumpc5):
The following is actually also really annoying when doing many
computations:
{{{
sage: P = PolynomialRing(QQ,3*5,"x"); x = P.gens(); M = Matrix(3,x)
sage: M
[ x0 x1 x2 x3 x4]
[ x5 x6 x7 x8 x9]
[x10 x11 x12 x13 x14]
sage: I = P.ideal(M.minors(2))
sage: I.groebner_fan()
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call
last)
...
RuntimeError: Ring variables cannot contain each other as prefixes
}}}
