Theorem reprf 31957
 Description: Members of the representation of 𝑀 as the sum of 𝑆 nonnegative integers from set 𝐴 as functions. (Contributed by Thierry Arnoux, 5-Dec-2021.)
Hypotheses
Ref Expression
reprval.a (𝜑𝐴 ⊆ ℕ)
reprval.m (𝜑𝑀 ∈ ℤ)
reprval.s (𝜑𝑆 ∈ ℕ0)
reprf.c (𝜑𝐶 ∈ (𝐴(repr‘𝑆)𝑀))
Assertion
Ref Expression
reprf (𝜑𝐶:(0..^𝑆)⟶𝐴)

Proof of Theorem reprf
Dummy variables 𝑐 𝑎 are mutually distinct and distinct from all other variables.
