Distinct variable groups:   𝑥,𝐴   𝑥,𝐵   𝑥,𝐶   𝑥,𝑓,𝐹   𝑓,𝐺,𝑥   𝜑,𝑓   𝑥,𝐷   𝑆,𝑓   𝑇,𝑓   𝑥,𝑊   𝑥,𝑍

Allowed substitution hints:   𝜑(𝑥)   𝐴(𝑓)   𝐵(𝑓)   𝐶(𝑓)   𝐷(𝑓)   𝑆(𝑥)   𝑇(𝑥)   𝑈(𝑥, 𝑓)   𝑉(𝑥, 𝑓)   𝑊(𝑓)   𝑋(𝑥, 𝑓)   𝑌(𝑥, 𝑓)   𝑍(𝑓)

Proof of Theorem mapfien

Dummy variable 𝑔 is distinct from all other variables.
