% 7.25/7.24 % SZS status Unsatisfiable
% 7.25/7.24 % SZS output start Proof
% 7.25/7.24 The input problem is unsatisfiable because
% 7.25/7.24
% 7.25/7.24 [1] the following set of Horn clauses is unsatisfiable:
% 7.25/7.24
% 7.25/7.24 product(identity, X, X)
% 7.25/7.24 product(X, identity, X)
% 7.25/7.24 product(inverse(X), X, identity)
% 7.25/7.24 product(X, inverse(X), identity)
% 7.25/7.24 product(X, Y, multiply(X, Y))
% 7.25/7.24 product(X, Y, Z) & product(X, Y, W) ==> Z = W
% 7.25/7.24 product(X, Y, U) & product(Y, Z, V) & product(U, Z, W) ==> product(X, V, W)
% 7.25/7.24 product(X, Y, U) & product(Y, Z, V) & product(X, V, W) ==> product(U, Z, W)
% 7.25/7.24 product(a, b, identity)
% 7.25/7.24 product(b, a, identity) ==> \bottom
% 7.25/7.24
% 7.25/7.24 This holds because
% 7.25/7.24
% 7.25/7.24 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
