Waow, great, Franklin, thanks!
I've just found another zeroless 3-digit infinite seq:
1 2 11 12 21 22 121 122 221 222 1221 1222 2221 2222 ...
1 9 1 9 1 99 1 99 1 999 1 999 1
Best,
É.

That would be (view with fixed width font):
1,2,3,6,12,13,16,22,23,26,32,33,36,62,
1 1 3 6 1 3 6 1 3 6 1 3 26 1
63,66,132,133,136,162,163,166,232,233,
3 66 1 3 26 1 3 66 1 3
236,262,263,266,332,333,336,362,363,
26 1 3 66 1 3 26 1 3
366,632,633,636,662,663,666,1332
266 1 3 26 1 3 666
Starting 1,2,3,4 or 1,2,3,5, no next term is possible, so this is
minimal. From the above, it should be clear that the sequence can be
extended indefinitely.

What would be the lexicographically first 4-digit seq?
Best,
