(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A243992 The sequence can be seen as a succession of digit-chunks ending in "1". The digit-size of each chunk is given by the sequence itself. No term is repeated. This is the lexically first sequence with the property. 1
1, 2, 10, 3, 4, 5, 6, 7, 8, 9, 21, 20, 12, 22, 13, 23, 31, 24, 25, 41, 26, 27, 28, 14, 29, 30, 32, 15, 33, 34, 35, 51, 36, 37, 38, 39, 40, 42, 43, 44, 45, 46, 16, 47, 48, 49, 50, 52, 53, 54, 55, 56, 17 (list; graph; refs; listen; history; text; internal format)
OFFSET

1,2

COMMENTS

All integers appear in the sequence, except the ones that have two or more consecutive 1's (like 11,110,111,112,113,...).

LINKS

EXAMPLE

If we put a vertical stroke right after each "1", the sequence becomes:

1|2,1|0,3,4,5,6,7,8,9,21|20,1|2,22,1|3,23,31|24,25,41|26,27,28,1|4,29,30,32,1|5... Now count the digits between two strokes: you'll get 1,2,10,3,4,5,6,7,8,... which is the sequence itself.
