COMMENTS

A158124: initial digit may not be changed to a zero (and hence give a number with fewer digits).

A050249: initial digit may be changed to a zero.

For the following values 5, 6, 7, 8, 9, 10 of k, the number of terms < 10^k in this sequence is 0, 1, 8, 72, 589, 4977. - Jean-Marc Rebert, Nov 10 2015
