% 0.18/0.44  % SZS output start Proof
% 0.18/0.44  The input problem is unsatisfiable because
% 0.18/0.44  
% 0.18/0.44  [1] the following set of Horn clauses is unsatisfiable:
% 0.18/0.44  
% 0.18/0.44  	less_equal(X, Y) ==> quotient(X, Y, zero)
% 0.18/0.44  	quotient(X, Y, zero) ==> less_equal(X, Y)
% 0.18/0.44  	quotient(X, Y, Z) ==> less_equal(Z, X)
% 0.18/0.44  	quotient(X, Y, V1) & quotient(Y, Z, V2) & quotient(X, Z, V3) & quotient(V3, V2, V4) & quotient(V1, Z, V5) ==> less_equal(V4, V5)
% 0.18/0.44  	less_equal(zero, X)
% 0.18/0.44  	less_equal(X, Y) & less_equal(Y, X) ==> X = Y
% 0.18/0.44  	less_equal(X, identity)
% 0.18/0.44  	quotient(X, Y, divide(X, Y))
% 0.18/0.44  	quotient(X, Y, Z) & quotient(X, Y, W) ==> Z = W
% 0.18/0.44  	quotient(zero, x, zero) ==> \bottom
% 0.18/0.44  
% 0.18/0.44  This holds because
% 0.18/0.44  
% 0.18/0.44  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):

% 0.18/0.44  	f4(true__, V4, V5) = less_equal(V4, V5)
% 0.18/0.44  	f5(true__, X, Y, V1, V4, V5) = f4(quotient(X, Y, V1), V4, V5)
