[Metamath] Question abouot indistopon

2024-04-23 Thread 'B. Wilson' via Metamath
The A e. V antecedent is confusing me. Might I ask for a quick pointer? 85195 indistopon $p |- ( A e. V -> { (/) , A } e. ( TopOn ` A ) ) $= ... $. It looks suspiciously close to A e. _V which reas as "A is a set", but in this case the V is just floating. What are the semantics here? --
