COMMENTS

For all known terms of this sequence, a(n+1) < a(n)+3; is this true for all terms? - Farideh Firoozbakht, Dec 20 2014

Integers not in this sequence begin: 13, 31, 34, 51, 54, 56, 58.

The comment above could also be phrased as "no two consecutive numbers in the complement" or "no gaps larger than one". But one sees that the missing numbers become more frequent towards larger values, so the answer to the question might well be "no". - Robert Price, Jan 06 2015
