This works:
{{{
sage: sr = mq.SR(1,2,2,4,gf2=True, polybori=True, order='deglex')
sage: F,s = sr.polynomial_system()
sage: F.eliminate_linear_variables()
Polynomial Sequence with 103 Polynomials in 55 Variables
}}}
This doesn't:
{{{
sage: sr = mq.SR(1,2,2,4,gf2=True, polybori=True, order='degrevlex')
sage: F,s = sr.polynomial_system()
sage: F.eliminate_linear_variables()
...
IndexError: index of root must be less than the values of roots of the
branches.
}}}
