#15644 new defect

make polynomial ring groaner fan work with many numbered variables

Description

See this ask.sagemath question.

sage: X=[var('x%d' % i) for i in range(20)]
sage: R=PolynomialRing(QQ,"x",11)
sage: R.ideal(x0).groebner_fan()
RuntimeError: Ring variables cannot contain each other as prefixes

Presumably this is because of some other software that has this limitation which computes the fan? I hope I'm understanding the post correctly.
