% 6.61/6.71 % SZS output start Proof
% 6.61/6.71 The input problem is unsatisfiable because
% 6.61/6.71
% 6.61/6.71 [1] the following set of Horn clauses is unsatisfiable:
% 6.61/6.71
% 6.61/6.71 mult(A, ld(A, B)) = B
% 6.61/6.71 ld(A, mult(A, B)) = B

% 6.61/6.71
% 6.61/6.71 This holds because
% 6.61/6.71
% 6.61/6.71 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
