The fact that they are necessary and sufficient would require more than these counter-examples.

  • 01:09 01:09, 2 April 2022 diff hist −343 Converse relationRemoved nonsensical comment. The set of all subsets of U is the power set of U, P(U). This means "The power set of all subsets of U" would be P(P(U)). If this is the domain of discourse for the converse of set membership and the RHS is a subset of this domain of discourse then the RHS would be an element of P(P(P(U))). This is clearly false. In truth, the domain of either sides just flips to the other in the converse.
