What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: ~w_3. p_14 <-> w_3. r -> p_14. p <-> p_1. p_1 -> r.
p_1 -> p_14 can be inferred via the transitivity rule. p_14 -> w_3 can be inferred via the biconditional elimination rule. p -> p_1 can be inferred via the biconditional elimination rule. w_3 -> p_14 can be inferred via the biconditional elimination rule. p_1 -> p can be inferred via the biconditional elimination rule. ~p_14 can be inferred via the biconditional elimination rule.
