Theorem frecuzrdgrclt 10139
Description: The function  R (used in the definition of the recursive definition generator on upper integers) yields ordered pairs of integers and elements of  S. Similar to frecuzrdgrcl 10134 except that  S and  T need not be the same. (Contributed by Jim Kingdon, 22-Apr-2022.)

Distinct variable groups:    x, C, y   
x, F, y    x, S, y    x, T, y    ph, x, y
Allowed substitution hints:    A( x, y)    R( x, y)

Proof of Theorem frecuzrdgrclt
Dummy variable  z is distinct from all other variables.
