Hi!
I think the problem is quite hard using Gröbner bases, I also talked
to Gregory Bard about the topic in Sage days 10.
Nevertheless it is interesting.
Did you convert the polynomial system to cnf using Martins converter.
Does it also solve the bigger problem, you gave me?
Can you please give

The problem in my case is really one of scale. I have put a larger
example at the bottom of this message. When I try to find the
groebner basis in sage 4.1 (which seems to use polybori-0.5rc.p8) the
memory usage goes over 1.6GB and then sage crashes. It is possible
that it just isn't

Hi!
I can't sleep, when fearing PolyBoRi could calculate wrong:
Actually, it's probably just about the wrapper.
My CVS, which is very much the same as 0.6.3 gives me:
l=a111,a112,a121,a122,b111,b112,b211,b212,c111,c112.split(,)
In [2]:declare_ring(l, globals())

Thanks very much for the reply.
Finally, for solving you should use a lexicographical term ordering:
sage: R.a111,a112,a121,a122,b111,b112,b211,b212,c111,c112 =
BooleanPolynomialRing(order='lex')
sage: I=(a111 * b111 * c111 + a112 * b112 * c112 - 1 , a111 * b211 * c111 +
: a112 * b212
bump, since there was no answer so far and despite i don't know the
answer it should be rather simple ... ?

Harald, thank you for reminding us of this post.
Raphael,
Actually I started an answer a while ago, but thought it wouldn't be
helpful and therefore didn't post it.
