% 14.48/14.60 % SZS output start Proof
% 14.48/14.60 The input problem is unsatisfiable because
% 14.48/14.60
% 14.48/14.60 [1] the following set of Horn clauses is unsatisfiable:
% 14.48/14.60
% 14.48/14.60 multiply(A, multiply(multiply(inverse(multiply(A, B)), C), B)) = C
% 14.48/14.60 multiply(a, b) = multiply(b, a) ==> \bottom
% 14.48/14.60
% 14.48/14.60 This holds because
% 14.48/14.60
% 14.48/14.60 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 14.48/14.60

% 14.48/14.60 f1(multiply(a, b)) = true__
% 14.48/14.60 f1(multiply(b, a)) = false__
% 14.48/14.60 multiply(A, multiply(multiply(inverse(multiply(A, B)), C), B)) = C

% 14.48/14.60 true__ = false__
% 14.48/14.60
% 14.48/14.60 This holds because
% 14.48/14.60
% 14.48/14.60 [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
