Theorem islss3 20136

Description: A linear subspace of a module is a subset which is a module in its own right. (Contributed by Stefan O'Rear, 6-Dec-2014.) (Revised by Mario Carneiro, 30-Apr-2015.)

**Hypotheses**
Ref	Expression
islss3.x	⊢ 𝑋 = (𝑊 ↾_s 𝑈)
islss3.v	⊢ 𝑉 = (Base‘𝑊)
islss3.s	⊢ 𝑆 = (LSubSp‘𝑊)

**Assertion**
Ref	Expression
islss3	⊢ (𝑊 ∈ LMod → (𝑈 ∈ 𝑆 ↔ (𝑈 ⊆ 𝑉 ∧ 𝑋 ∈ LMod)))

Proof of Theorem islss3 Dummy variables 𝑎 𝑏 𝑥 are mutually distinct and distinct from all other variables.
