%N Numbers that can appear an infinite number of times in a variation of A097390.
%e The number 12 appears infinitely often in any sequence based on a variation of the A097390 sentence ("This sentence contains the twentieth, eighth, ninth ... letters of the English alphabet, in order") that contains a "k" or "l" in the prologue (e.g. "This sentence, amazingly, contains the twentieth, eighth, ninth ..."). Otherwise, it does not appear at all. The other members of the sequence must appear infinitely often in any sequence based on any English variation of A097390 that generates an infinite string of ordinal number-words (cf. A096828).
%Y Cf. A005224, A097389, A097390, A096828, A097395.
