% 4.68/5.09  original problem:
% 4.68/5.09  axioms:
% 4.68/5.09  multiply(multiply(A, inverse(A), B), inverse(multiply(multiply(C, D, E), F, multiply(C, D, G))), multiply(D, multiply(G, F, E), C)) = B
% 4.68/5.09  goal:
% 4.68/5.09  multiply(a(), a(), b()) != a()
% 4.68/5.09  To show the unsatisfiability of the original goal,
% 4.68/5.09  it suffices to show that multiply(a(), a(), b()) = a() (skolemized goal) is valid under the axioms.
