% 4.23/4.30 % SZS output start Proof
% 4.23/4.30 The input problem is unsatisfiable because
% 4.23/4.30
% 4.23/4.30 [1] the following set of Horn clauses is unsatisfiable:
% 4.23/4.30
% 4.23/4.30 mult(A, ld(A, B)) = B
% 4.23/4.30 ld(A, mult(A, B)) = B

% 4.23/4.30 rd(mult(A, B), B) = A

% 4.23/4.30 mult(unit, A) = A
% 4.23/4.30 mult(i(A), mult(A, B)) = B

% 4.23/4.30 mult(mult(a, b), a) = mult(a, mult(b, a)) ==> \bottom
% 4.23/4.30
% 4.23/4.30 This holds because
% 4.23/4.30
% 4.23/4.30 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
