Theorem iccpartgt 47419

Description: If there is a partition, then all intermediate points and the bounds are strictly ordered. (Contributed by AV, 18-Jul-2020.)

**Hypotheses**
Ref	Expression
iccpartgtprec.m	⊢ (𝜑 → 𝑀 ∈ ℕ)
iccpartgtprec.p	⊢ (𝜑 → 𝑃 ∈ (RePart‘𝑀))

**Assertion**
Ref	Expression
iccpartgt	⊢ (𝜑 → ∀𝑖 ∈ (0...𝑀)∀𝑗 ∈ (0...𝑀)(𝑖 < 𝑗 → (𝑃‘𝑖) < (𝑃‘𝑗)))

Distinct variable groups: 𝑖,𝑀 𝑃,𝑖 𝜑,𝑖 𝑗,𝑀 𝑃,𝑗,𝑖 𝜑,𝑗

Proof of Theorem iccpartgt Dummy variable 𝑘 is distinct from all other variables.
