Theorem pnfnei 21246
 Description: A neighborhood of +∞ contains an unbounded interval based at a real number. Together with xrtgioo 22830 (which describes neighborhoods of ℝ) and mnfnei 21247, this gives all "negative" topological information ensuring that it is not too fine (and of course iooordt 21243 and similar ensure that it has all the sets we want). (Contributed by Mario Carneiro, 3-Sep-2015.)

pnfnei ((𝐴 ∈ (ordTop‘ ≤ ) ∧ +∞ ∈ 𝐴) → ∃𝑥 ∈ ℝ (𝑥(,]+∞) ⊆ 𝐴)
Distinct variable group:   𝑥,𝐴

Proof of Theorem pnfnei
Dummy variables 𝑎 𝑏 𝑐 𝑢 𝑦 are mutually distinct and distinct from all other variables.
