Theorem frlmrcl 22096
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.
