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: t -> w_2. w_2 -> t_3. forall x_24: ~R_24(x_24). R_24(a_24) <-> t_3. p_6 -> t.
t -> t_3 can be inferred via the transitivity rule. p_6 -> w_2 can be inferred via the transitivity rule. R_24(a_24) -> t_3 can be inferred via the biconditional elimination rule. t_3 -> R_24(a_24) can be inferred via the biconditional elimination rule.
