[seqfan] Re: Seq and First diff use only a 3-digit alphabet

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?
