% 0.19/0.63  The input problem is unsatisfiable because
% 0.19/0.63  
% 0.19/0.63  [1] the following set of Horn clauses is unsatisfiable:
% 0.19/0.63  
% 0.19/0.63  	c_lessequals(V_B, V_A, tc_set(T_a)) & c_lessequals(V_A, V_B, tc_set(T_a)) ==> V_A = V_B
% 0.19/0.63  	c_lessequals(v_n, c_Union(v_Y, tc_set(t_a)), tc_set(tc_set(t_a)))
% 0.19/0.63  	c_lessequals(c_Union(v_Y, tc_set(t_a)), v_n, tc_set(tc_set(t_a)))
% 0.19/0.63  	v_n = c_Union(v_Y, tc_set(t_a)) ==> \bottom
% 0.19/0.63  
% 0.19/0.63  This holds because
% 0.19/0.63  
% 0.19/0.63  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.19/0.63  
% 0.19/0.63  E:
% 0.19/0.63  	c_lessequals(c_Union(v_Y, tc_set(t_a)), v_n, tc_set(tc_set(t_a))) = true__
% 0.19/0.63  	c_lessequals(v_n, c_Union(v_Y, tc_set(t_a)), tc_set(tc_set(t_a))) = true__

% 0.19/0.63  
% 0.19/0.63  This holds because
% 0.19/0.63  
% 0.19/0.63  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 0.19/0.63

% 0.19/0.63  	c_Union(v_Y, tc_set(t_a)) -> v_n
