This my seventh attempt at trying to formalize the John function, ...

ZFC Language:
If L= ZFC set theory, then L = { { }, ( ), [ ], V1, V2, …,C1, C2, …, f1a(f1), f2a(f2), …, =,}
Where V are variables, C are constants, f^i is a i-ary function symbol, where a(function) assigns a natural number as the function’s “aray” (For example, f1a(f1) could make it so that f1 is a 3-ary function).” is "not," is the empty set, and | is ¨such that"
Define Johns function as follows:
-"For any two functions f and g, f[>]g is true if is true"
-"For any two functions f and g, f[=]g is true if is true."
-For any formula F, sym(F) = The amount of symbols in formula F.
-For any finite set, A, define max(A) as .
-For any function f, and any ZFC formula F, is true if the function f is described by the formula F.
-For any set of functions, S,
", where Fx = , and where F and z in the Fx definition are ZFC formulae"
