COMMENTS

The "may" in the definition should clarify that, e.g., 22900 is in the sequence since it may represent a date (Feb. 29), but not necessarily in any century (e.g., in 2000 but not in 1900), but 22900+k is present only for k=0 (mod 4).

The sequence is finite, with 366*25 + 365*75 terms, cf. comment from G. Resta in A213182. The largest term is a(36525)=123199.

EXAMPLE

a(1)=10100 represents, e.g., Jan 01 1900 (or Jan 01 2000).

a(100)=10199 (for Jan 01 1999) is followed by a(101)=10200 (for Jan 02 2000).

a(3100)=13199 (for Jan 31 1999) is followed by a(3101)=20100 (for Feb 01 2000).

CROSSREFS

Cf. A213182, A106605, A107273, A107275; A210883, A210884, A210885.
