Theorem mirimanoffr 36529

Description: Relative version of mirimanoff 36530 (which corresponds to the case 𝑉 = V).

Note that the definition of 𝑀 presupposes that ω is available as a set (omex 9645), which is equivalent to assuming ax-inf2 9643. (Contributed by Adrian Ducourtial, 13-Oct-2026.)

Hypothesis

Ref	Expression
mirimanoffr.1	⊢ 𝑀 = {𝑥 ∈ 𝑉 ∣ ¬ ∃𝑓(𝑓 Fn ω ∧ (𝑓‘∅) = 𝑥 ∧ ∀𝑛 ∈ ω (𝑓‘suc 𝑛) ∈ (𝑓‘𝑛))}

Assertion

Ref	Expression
mirimanoffr	⊢ 𝑀 ∉ 𝑉

Distinct variable groups:   𝑓,𝑛,𝑥,𝑀   𝑓,𝑉,𝑛,𝑥

Proof of Theorem mirimanoffr

Dummy variables 𝑚 𝑔 are mutually distinct and distinct from all other variables.
