COMMENTS

Proofs still needed that all the examples on the left hand side cannot fit on the right hand side as well, and that EX9881 cannot fit on the left hand side as well.

CROSSREFS

The left hand side implies the left hand side of BP1116.

The right hand side does not imply the right hand side of BP1116. (EX9881 is meant to be a counterexample.)
