Description: An associative (closed internal binary) operation for a set. (Contributed by AV, 20-Jan-2020.)

Assertion

Ref	Expression
assintop	|- ( .o. e. ( assIntOp ` M ) -> ( .o. : ( M X. M ) --> M /\ .o. assLaw M ) )

Proof of Theorem assintop

Dummy variable o is distinct from all other variables.
