Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

COMMENTS

The sequence starts with a(1)=1 and was always extended with the smallest integer not yet used that does not lead to a contradiction.

EXAMPLE

The blocks of digits "1" are indicated here by parentheses; the successive block-sizes are 1, 2, 3, 4,... which reproduces the sequence itself:

(1),2,3,4,5,6,7,8,9,(11),20,2(1,11)0,22,23,24,25,26,27,28,29,30,3(1,111),32,33,...
