Hypotheses

Ref	Expression
mndtcbas.c	⊢ (𝜑 → 𝐶 = (MndToCat‘𝑀))
mndtcbas.m	⊢ (𝜑 → 𝑀 ∈ Mnd)

Assertion

Ref	Expression
mndtcval	⊢ (𝜑 → 𝐶 = {⟨(Base‘ndx), {𝑀}⟩, ⟨(Hom ‘ndx), {⟨𝑀, 𝑀, (Base‘𝑀)⟩}⟩, ⟨(comp‘ndx), {⟨⟨𝑀, 𝑀, 𝑀⟩, (+g‘𝑀)⟩}⟩})

Proof of Theorem mndtcval

Dummy variable 𝑚 is distinct from all other variables.
