Theorem frlmrcl 20603

Description: If a free module is inhabited, this is sufficient to conclude that the ring expression defines a set. (Contributed by Stefan O'Rear, 3-Feb-2015.)

Hypotheses

Ref	Expression
frlmval.f	⊢ 𝐹 = (𝑅 freeLMod 𝐼)
frlmrcl.b	⊢ 𝐵 = (Base‘𝐹)

Assertion

Ref	Expression
frlmrcl	⊢ (𝑋 ∈ 𝐵 → 𝑅 ∈ V)

Proof of Theorem frlmrcl

Dummy variables 𝑟 𝑖 are mutually distinct and distinct from all other variables.
