Theorem sseqval 29777
 Description: Value of the strong sequence builder function. The set 𝑊 represents here the words of length greater than or equal to the lenght of the initial sequence 𝑀. (Contributed by Thierry Arnoux, 21-Apr-2019.)

sseqval.1 (𝜑𝑆 ∈ V)
sseqval.2 (𝜑𝑀 ∈ Word 𝑆)
sseqval.3 𝑊 = (Word 𝑆 ∩ (# “ (ℤ‘(#‘𝑀))))
sseqval.4 (𝜑𝐹:𝑊𝑆)
Assertion
Ref Expression
sseqval (𝜑 → (𝑀seqstr𝐹) = (𝑀 ∪ ( lastS ∘ seq(#‘𝑀)((𝑥 ∈ V, 𝑦 ∈ V ↦ (𝑥 ++ ⟨“(𝐹𝑥)”⟩)), (ℕ0 × {(𝑀 ++ ⟨“(𝐹𝑀)”⟩)})))))

Allowed substitution hints:   𝑆(𝑥,𝑦)   𝑊(𝑥,𝑦)

Proof of Theorem sseqval
Dummy variables 𝑓 𝑚 are mutually distinct and distinct from all other variables.
