Description: A class of transitive sets is partially ordered by E. (Contributed by Scott Fenton, 15-Oct-2010.)

Assertion

Ref	Expression
elpotr	⊢ (∀𝑧 ∈ 𝐴 Tr 𝑧 → E Po 𝐴)

Distinct variable group:   𝑧,𝐴

Proof of Theorem elpotr

Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
