Theorem cvmliftiota 35483

Description: Write out a function 𝐻 that is the unique lift of 𝐹. (Contributed by Mario Carneiro, 16-Feb-2015.)

**Hypotheses**
Ref	Expression
cvmliftiota.b	⊢ 𝐵 = ∪ 𝐶
cvmliftiota.h	⊢ 𝐻 = (℩𝑓 ∈ (II Cn 𝐶)((𝐹 ∘ 𝑓) = 𝐺 ∧ (𝑓‘0) = 𝑃))
cvmliftiota.f	⊢ (𝜑 → 𝐹 ∈ (𝐶 CovMap 𝐽))
cvmliftiota.g	⊢ (𝜑 → 𝐺 ∈ (II Cn 𝐽))
cvmliftiota.p	⊢ (𝜑 → 𝑃 ∈ 𝐵)
cvmliftiota.e	⊢ (𝜑 → (𝐹‘𝑃) = (𝐺‘0))

**Assertion**
Ref	Expression
cvmliftiota	⊢ (𝜑 → (𝐻 ∈ (II Cn 𝐶) ∧ (𝐹 ∘ 𝐻) = 𝐺 ∧ (𝐻‘0) = 𝑃))

Distinct variable groups: 𝐶,𝑓 𝑓,𝐹 𝑓,𝐺 𝑃,𝑓 Allowed substitution hints: 𝜑(𝑓) 𝐵(𝑓) 𝐻(𝑓) 𝐽(𝑓)

Proof of Theorem cvmliftiota Dummy variable 𝑔 is distinct from all other variables.
