mnuop23d.1 𝑀 = {𝑘 ∣ ∀𝑙𝑘 (𝒫 𝑙𝑘 ∧ ∀𝑚𝑛𝑘 (𝒫 𝑙𝑛 ∧ ∀𝑝𝑙 (∃𝑞𝑘 (𝑝𝑞𝑞𝑚) → ∃𝑟𝑚 (𝑝𝑟 𝑟𝑛))))}

Ref Expression
mnuop23d (𝜑 → ∃𝑤𝑈 (𝒫 𝐴𝑤 ∧ ∀𝑖𝐴 (∃𝑣𝑈 (𝑖𝑣𝑣𝐹) → ∃𝑢𝐹 (𝑖𝑢 𝑢𝑤))))
Distinct variable groups:   𝑣,𝐹   𝑤,𝐴,𝑖   𝑤,𝑢,𝐹,𝑖   𝑤,𝑣,𝑈,𝑘,𝑚,𝑛,𝑞,𝑝,𝑙,𝑖   𝑤,𝑟   𝑢,𝑈,𝑘,𝑚,𝑛,𝑟,𝑝,𝑙,𝑖
Allowed substitution hints:   𝜑(𝑤,𝑣,𝑢,𝑖,𝑘,𝑚,𝑛,𝑟,𝑞,𝑝,𝑙)   𝐴(𝑣,𝑢,𝑘,𝑚,𝑛,𝑟,𝑞,𝑝,𝑙)   𝐹(𝑘,𝑚,𝑛,𝑟,𝑞,𝑝,𝑙)   𝑀(𝑤,𝑣,𝑢,𝑖,𝑘,𝑚,𝑛,𝑟,𝑞,𝑝,𝑙)   𝑉(𝑤,𝑣,𝑢,𝑖,𝑘,𝑚,𝑛,𝑟,𝑞,𝑝,𝑙)

Proof of Theorem mnuop23d
