i think its just reffering to vector space dimension I have no idea what the Krull dimension of this space is Also if i try lex in QQ the grobner basis i get out is [x + y + z - 3, y^2 + y*z - 3*y + z^2 - 3*z + 2, z^3 - 3*z^2 + 2*z + 2/3] -- To post to this group, send email to

I observed that solve behaves inconsistently in the following regards: sage: solve([x==1,x==-1],x) [] (this is as expected) However: solve([x==1,x==-1],x, solution_dict=True) produces an error message. Easy to live with, but I was scared when I first saw it :-). It should be easy to correct,
