Theorem trpredmintr 31731

Description: The transitive predecessors form the smallest class transitive in 𝑅 and 𝐴. That is, if 𝐵 is another 𝑅, 𝐴 transitive class containing Pred(𝑅, 𝐴, 𝑋), then TrPred(𝑅, 𝐴, 𝑋) ⊆ 𝐵 (Contributed by Scott Fenton, 25-Apr-2012.) (Revised by Mario Carneiro, 26-Jun-2015.)

**Assertion**
Ref	Expression
trpredmintr	⊢ (((𝑋 ∈ 𝐴 ∧ 𝑅 Se 𝐴) ∧ (∀𝑦 ∈ 𝐵 Pred(𝑅, 𝐴, 𝑦) ⊆ 𝐵 ∧ Pred(𝑅, 𝐴, 𝑋) ⊆ 𝐵)) → TrPred(𝑅, 𝐴, 𝑋) ⊆ 𝐵)

Distinct variable groups: 𝑦,𝐴 𝑦,𝐵 𝑦,𝑅 𝑦,𝑋

Proof of Theorem trpredmintr Dummy variables 𝑎 𝑐 𝑑 𝑖 𝑗 𝑘 are mutually distinct and distinct from all other variables.
