Theorem mdandyvrx1 41149

Description: Given the exclusivities set in the hypotheses, there exist a proof where ch, th, ta, et exclude ze, si accordingly. (Contributed by Jarvin Udandy, 7-Sep-2016.)

Hypotheses

Ref	Expression
mdandyvrx1.1	|- ( ph \/_ ze )

mdandyvrx1.4	|- ( th <-> ph )
mdandyvrx1.5	|- ( ta <-> ph )
mdandyvrx1.6	|- ( et <-> ph )

Assertion

Ref	Expression
mdandyvrx1	|- ( ( ( ( ch \/_ si ) /\ ( th \/_ ze ) ) /\ ( ta \/_ ze ) ) /\ ( et \/_ ze ) )
