 A213184 Numbers which may represent a date in "condensed American notation" MMDDYY. 3
 10100, 10101, 10102, 10103, 10104, 10105, 10106, 10107, 10108, 10109, 10110, 10111, 10112, 10113, 10114, 10115, 10116, 10117, 10118, 10119, 10120, 10121, 10122, 10123, 10124, 10125, 10126, 10127, 10128, 10129, 10130, 10131, 10132, 10133, 10134, 10135, 10136, 10137, 10138, 10139, 10140 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 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. LINKS 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.
