% 0.12/0.40 The input problem is unsatisfiable because
% 0.12/0.40
% 0.12/0.40 [1] the following set of Horn clauses is unsatisfiable:
% 0.12/0.40
% 0.12/0.40 meet(X, join(X, Y)) = X
% 0.12/0.40 join(X, meet(X, Y)) = X
% 0.12/0.40 meet(X, Y) = meet(Y, X)
% 0.12/0.40 join(X, Y) = join(Y, X)
% 0.12/0.40 meet(meet(X, Y), Z) = meet(X, meet(Y, Z))
% 0.12/0.40 join(join(X, Y), Z) = join(X, join(Y, Z))
% 0.12/0.40 meet(xx, xx) = xx ==> \bottom
% 0.12/0.40
% 0.12/0.40 This holds because
% 0.12/0.40
% 0.12/0.40 [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):

% 0.12/0.40

% 0.12/0.40 meet(Y2, meet(Y0, Y1)) = meet(Y0, meet(Y1, Y2))
