Theorem grutsk1 9522

Description: Grothendieck universes are the same as transitive Tarski classes, part one: a transitive Tarski class is a universe. (The hard work is in tskuni 9484.) (Contributed by Mario Carneiro, 17-Jun-2013.)

Assertion

Ref	Expression
grutsk1	⊢ ((𝑇 ∈ Tarski ∧ Tr 𝑇) → 𝑇 ∈ Univ)

Proof of Theorem grutsk1

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