Theorem lgsval4a 15695

Description: Same as lgsval4 15693 for positive 𝑁. (Contributed by Mario Carneiro, 4-Feb-2015.)

**Hypothesis**
Ref	Expression
lgsval4.1	⊢ 𝐹 = (𝑛 ∈ ℕ ↦ if(𝑛 ∈ ℙ, ((𝐴 /_L 𝑛)↑(𝑛 pCnt 𝑁)), 1))

**Assertion**
Ref	Expression
lgsval4a	⊢ ((𝐴 ∈ ℤ ∧ 𝑁 ∈ ℕ) → (𝐴 /_L 𝑁) = (seq1( · , 𝐹)‘𝑁))

Distinct variable groups: 𝐴,𝑛 𝑛,𝑁 Allowed substitution hint: 𝐹(𝑛)

Proof of Theorem lgsval4a Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
