Theorem pnfnei 21072
Description: A neighborhood of +∞ contains an unbounded interval based at a real number. Together with xrtgioo 22656 (which describes neighborhoods of ) and mnfnei 21073, this gives all "negative" topological information ensuring that it is not too fine (and of course iooordt 21069 and similar ensure that it has all the sets we want). (Contributed by Mario Carneiro, 3-Sep-2015.)
