 A244602 First repdigit number with n digits occurring in the decimal expansion of e, starting after the decimal point. 6
 7, 66, 999, 8888, 66666, 0, 5555555, 99999999, 111111111, 1111111111 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS A244601 allows consecutive 0's and says "Resulting repdigits are A244602", so 000000 = 0 is apparently allowed here as a repdigit with 6 digits. Otherwise a(6) would be 555555 at position 210482 (which extends to a seventh 5). - Jens Kruse Andersen, Jul 20 2014 LINKS EXAMPLE Decimal expansion of e: 2.|7|18281828459045235360287471352|66|24977572470936|999|59574966967627724..
