% 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)):
% 19.57/19.61

% 19.57/19.61  	f6(true__, U, Z, W) = product(U, Z, W)
% 19.57/19.61  	f7(true__, X, Y, U, Z, W) = f6(product(X, Y, U), U, Z, W)
