This sequence is a permutation of the natural numbers (with inverse A283194 and fixed points A283206):
- for any k>0, 10^(k-1) is the first k-digit number appearing in this sequence, and the corresponding partial carryless sum is also the first k-digit number appearing in A283193,
- all powers of 10 appear in this sequence, in increasing order,
- if a(m)=10^k, and the least value not yet seen in this sequence, say v, is smaller than 10^k, then a(m+1)=v,
- hence each natural number will eventually appear in this sequence.
