%N Terms in Aronson's sequence (A005224) whose English ordinals do not contain the letter t.

%C The word "thousand", the -th suffix, the -st suffix, and the word "third" all contain the letter t, so all terms with at least 4 digits have the last 6 digits 000X02 where X is not 2, 3, or 8. - _J. Lowell_, Apr 24 2023

%H Hans Havermann, <a href="/A284744/b284744.txt">Table of n, a(n) for n = 1..308</a>

%e a(1) is 902 because 902 is the smallest term in A005224 whose ordinal (nine hundred second) contains no t.
