The same idea as in my previous post -- but with integers
(the "digit column b" spells the digits of the sequence):
digit column: a b c
1
2
3
4
5
6
7
8
9
10
2 0
1 2
3 0
1 1
2 1
1 3
4 0
1 4
1 5
2 2
1 6
1 7
2 3
2 4
5 0
1 8
3 4
1 9
2 5
2 6
2 7

The sequence 1,2,3,4,5,6,7,8,9,10,20,12,30,11,21,13,40,14,15,
22,16,17,23,24,50,18,34,19,25,26,27,...
is for sure a permutation of the Naturals.

If this "flagpole" concept is worth entering the OEIS,
one could add a lot of such sequences:
Fla*Prime would start: 2,3,5,7,11,15,17,23,19,37,29,31,41,59,37,47,...
Fla*Fibo would start: 0,1,1,2,3,5,8,13,34,233,144,21,46368,121393,...
Fla*Even would start: 2,4,6,8,10,20,12,30,14,22,32,40,16,24,26,28,...
----------
Best,
É.
