Consider the following premises. s <-> p. s -> ~S_17(j). forall x_17: S_3(x_17) or S_17(x_17). ~S_3(j). Can we infer p from them?
 From forall x_17: S_3(x_17) or S_17(x_17) we can infer S_3(j) or S_17(j). From S_3(j) or S_17(j), ~S_3(j) we can infer S_17(j). From s -> ~S_17(j), S_17(j) we can infer ~s. Finally, from s <-> p, ~s we can infer ~p, which contradicts p. Therefore, the answer is no.
