betti(GroebnerBasis) -- diagram of the degrees of a groebner basis

Synopsis

Description

Here is an example:
i1 : S = ZZ/10007[x,y];
i2 : G = gb ideal(x^3+y^3, x*y^4);
i3 : gens G

o3 = | x3+y3 xy4 y7 |

             1       3
o3 : Matrix S  <--- S
i4 : betti G

            0 1
o4 = total: 1 3
         0: 1 .
         1: . .
