Theorem iccelpart 41871
 Description: An element of any partitioned half opened interval of extended reals is an element of a part of this partition. (Contributed by AV, 18-Jul-2020.)
Assertion
Ref Expression
iccelpart (𝑀 ∈ ℕ → ∀𝑝 ∈ (RePart‘𝑀)(𝑋 ∈ ((𝑝‘0)[,)(𝑝𝑀)) → ∃𝑖 ∈ (0..^𝑀)𝑋 ∈ ((𝑝𝑖)[,)(𝑝‘(𝑖 + 1)))))
Distinct variable groups:   𝑖,𝑀,𝑝   𝑖,𝑋,𝑝

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