% 115.17/115.19 % SZS output start Proof
% 115.17/115.19 The input problem is unsatisfiable because
% 115.17/115.19
% 115.17/115.19 [1] the following set of Horn clauses is unsatisfiable:
% 115.17/115.19
% 115.17/115.19 implies(truth, X) = X
% 115.17/115.19 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 115.17/115.19 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 115.17/115.19 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 115.17/115.19 or(X, Y) = implies(not(X), Y)
% 115.17/115.19 or(or(X, Y), Z) = or(X, or(Y, Z))
% 115.17/115.19 or(X, Y) = or(Y, X)
% 115.17/115.19 and(X, Y) = not(or(not(X), not(Y)))
% 115.17/115.19 and(and(X, Y), Z) = and(X, and(Y, Z))
% 115.17/115.19 and(X, Y) = and(Y, X)
% 115.17/115.19 xor(X, Y) = or(and(X, not(Y)), and(not(X), Y))
% 115.17/115.19 xor(X, Y) = xor(Y, X)
% 115.17/115.19 and_star(X, Y) = not(or(not(X), not(Y)))
% 115.17/115.19 and_star(and_star(X, Y), Z) = and_star(X, and_star(Y, Z))
% 115.17/115.19 and_star(X, Y) = and_star(Y, X)
% 115.17/115.19 not(truth) = falsehood
% 115.17/115.19 xor(x, falsehood) = x ==> \bottom
% 115.17/115.19
% 115.17/115.19 This holds because
% 115.17/115.19
% 115.17/115.19 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 115.17/115.19
% 115.17/115.19 E:
% 115.17/115.19 and(X, Y) = and(Y, X)
% 115.17/115.19 and(X, Y) = not(or(not(X), not(Y)))
% 115.17/115.19 and(and(X, Y), Z) = and(X, and(Y, Z))
% 115.17/115.19 and_star(X, Y) = and_star(Y, X)
% 115.17/115.19 and_star(X, Y) = not(or(not(X), not(Y)))
% 115.17/115.19 and_star(and_star(X, Y), Z) = and_star(X, and_star(Y, Z))
% 115.17/115.19 f1(x) = false__
% 115.17/115.19 f1(xor(x, falsehood)) = true__
% 115.17/115.19 implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 115.17/115.19 implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 115.17/115.19 implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 115.17/115.19 implies(truth, X) = X
% 115.17/115.19 not(truth) = falsehood

% 115.17/115.19 or(or(X, Y), Z) = or(X, or(Y, Z))
% 115.17/115.19 xor(X, Y) = or(and(X, not(Y)), and(not(X), Y))
% 115.17/115.19 xor(X, Y) = xor(Y, X)

% 115.17/115.19
