% 19.57/19.61 % SZS output start Proof
% 19.57/19.61 The input problem is unsatisfiable because
% 19.57/19.61
% 19.57/19.61 [1] the following set of Horn clauses is unsatisfiable:
% 19.57/19.61
% 19.57/19.61 product(identity, X, X)
% 19.57/19.61 product(inverse(X), X, identity)
% 19.57/19.61 product(X, Y, multiply(X, Y))
% 19.57/19.61 product(X, Y, Z) & product(X, Y, W) ==> equalish(Z, W)
% 19.57/19.61 product(X, Y, U) & product(Y, Z, V) & product(U, Z, W) ==> product(X, V, W)
% 19.57/19.61 product(X, Y, U) & product(Y, Z, V) & product(X, V, W) ==> product(U, Z, W)
% 19.57/19.61 equalish(X, Y) & product(W, Z, X) ==> product(W, Z, Y)
% 19.57/19.61 equalish(a, b)
% 19.57/19.61 product(a, c, result)
% 19.57/19.61 product(b, c, result) ==> \bottom
% 19.57/19.61
% 19.57/19.61 This holds because
% 19.57/19.61
% 19.57/19.61 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
