 {{{
 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.
