Description: Concatenation with the reverse path. (Contributed by Mario Carneiro, 12-Feb-2015.)

**Hypotheses**
Ref	Expression
pcorev2.1	⊢ 𝐺 = (𝑥 ∈ (0[,]1) ↦ (𝐹‘(1 − 𝑥)))
pcorev2.2	⊢ 𝑃 = ((0[,]1) × {(𝐹‘0)})

**Assertion**
Ref	Expression
pcorev2	⊢ (𝐹 ∈ (II Cn 𝐽) → (𝐹(*_𝑝‘𝐽)𝐺)( ≃_ph‘𝐽)𝑃)

Distinct variable groups: 𝑥,𝐹 𝑥,𝐽 Allowed substitution hints: 𝑃(𝑥) 𝐺(𝑥)

Proof of Theorem pcorev2 Dummy variable 𝑦 is distinct from all other variables.
