 Description: volsup 23131 is incompatible with the Feferman-Levy model. (Contributed by Brendan Leahy, 2-Jan-2018.)
Hypothesis
Ref Expression
volsupnfl.0 ((𝑓:ℕ⟶dom vol ∧ ∀𝑛 ∈ ℕ (𝑓𝑛) ⊆ (𝑓‘(𝑛 + 1))) → (vol‘ ran 𝑓) = sup((vol “ ran 𝑓), ℝ*, < ))
Assertion
Ref Expression
volsupnfl ((𝐴 ≼ ℕ ∧ ∀𝑥𝐴 𝑥 ≼ ℕ) → 𝐴 ≠ ℝ)
Distinct variable group:   𝑓,𝑛,𝑥,𝐴

Proof of Theorem volsupnfl
Dummy variables 𝑔 𝑚 𝑙 are mutually distinct and distinct from all other variables.
