% 2.21/1.20  | Instantiating (0) with all_0_0_0, all_0_1_1, all_0_2_2, all_0_3_3 yields:

% 2.21/1.20  | Instantiating formula (10) with all_0_0_0 and discharging atoms is_state(all_0_0_0), yields:

% 2.21/1.20  | Instantiating formula (10) with all_0_3_3 and discharging atoms is_state(all_0_3_3), yields:

% 2.21/1.20  |
