Description: Lemma for enmap2 6068. Calculate the range of W. (Contributed by SF, 3-Mar-2015.)

Hypothesis

Ref	Expression
enmap1lem5.1	|- W = (s e. (A ^m G) |-> (r o. s))

Assertion

Ref	Expression
enmap1lem5	|- (r:A-1-1-onto->B -> ran W = (B ^m G))

Distinct variable groups:   G,s   s,r   A,s

Allowed substitution hints:   A(r)   B(s,r)   G(r)   W(s,r)

Proof of Theorem enmap1lem5

Dummy variable p is distinct from all other variables.
