 Annual Appeal: Please make a donation to keep the OEIS running. In 2018 we replaced the server with a faster one, added 20000 new sequences, and reached 7000 citations (often saying "discovered thanks to the OEIS"). Other ways to donate

 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

Erasing cyclically digits 1 --> 0 gives: . 1. 1. 2. 1.3 .2. 4.1. 5.3. which is the pattern of the sequence itself.
