Hints
(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A108710 Start to read the sequence digit by digit and erase the first "1" you encounter, then the "first "2", the first "3", etc., until the first "0"; go on from there and erase again the first "1", the first "2", etc., until "0" -- and so on, cyclically until the end of the (infinite) sequence. Concatenate what is left. The result is the concatenation of all integers of the sequence. 0

EXAMPLE

Sequence starts: 1 12 13 24 153 627 4819 5031... Erasing cyclically digits 1 --> 0 gives: . 1. 1. 2. 1.3 .2. 4.1. 5.3. which is the pattern of the sequence itself.
