%C A061511 In A061511-A061522, A061746-A061750 when the incremented digit exceeds 9 it is written as a 2-digit string. So 9+1 becomes the 2-digit string 10, etc.
%C A061511 a(n+10) is the concatenation of a(n) and a(n-1).
%C A061511 Considering each term as a sequence of digits, each of the subsequences a(9n), a(9n-1), ... and a(9n-8) converges to a different limit. - _M. F. Hasler_, Jun 24 2016
