proposed sequence: Digits of n are not present in 3n.

[Jonathan Post]

1, 2, 3, 4, 6, 7, 8, 9, 11, 12, 16, 18, 19, 21, 22, 23, 26, 27, 29, 32, 33, ...

Digits of n are not present in 3n.

This proposed sequence is to 3 as A038365 is to 2.

It would be a base sequence, but less arbitrary if we treated the array:
A[k,n] = n-th integer j whose digits are not in k*j, perhaps listed by
antidiagonals.

At all interesting?

There are so very many wonderful Math things on Erich Friedman's web site!
