Description: Reverse closure of a magma homomorphism. (Contributed by AV, 24-Feb-2020.)
Assertion
Ref Expression
mgmhmrcl  |-  ( F  e.  ( S MgmHom  T
)  ->  ( S  e. Mgm  /\  T  e. Mgm )
)

Proof of Theorem mgmhmrcl
Dummy variables  x  t  s  f  y are mutually distinct and distinct from all other variables.
