% 6.34/6.38 % SZS status Unsatisfiable
% 6.34/6.38 % SZS output start Proof
% 6.34/6.38 The input problem is unsatisfiable because
% 6.34/6.38
% 6.34/6.38 [1] the following set of Horn clauses is unsatisfiable:
% 6.34/6.38
% 6.34/6.38 product(X, Y, multiply(X, Y))
% 6.34/6.38 product(X, Y, Z) & product(X, Y, W) ==> Z = W
% 6.34/6.38 product(X, Y, U) & product(Y, Z, V) & product(U, Z, W) ==> product(X, V, W)
% 6.34/6.38 product(X, Y, U) & product(Y, Z, V) & product(X, V, W) ==> product(U, Z, W)
% 6.34/6.38 product(identity, A, A)
% 6.34/6.38 product(inverse(A), A, identity)
% 6.34/6.38 product(a, A, identity) ==> \bottom
% 6.34/6.38
% 6.34/6.38 This holds because
% 6.34/6.38
% 6.34/6.38 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 6.34/6.38
% 6.34/6.38 E:
% 6.34/6.38 f1(true__, Z, W) = Z
% 6.34/6.38 f2(product(X, Y, W), X, Y, Z, W) = W

% 6.34/6.38 G:

% 6.34/6.38
% 6.34/6.38 This holds because
