Honsberger is not defining n-persistent that way; he defines it as at
least the first n multiples are pandigital, not exactly. So really,
this result is simply that there are arbitrarily persistent numbers.
I have submitted a change to standardize the terminology in A204047.

Hmm. One of the first exercises in the Honsberger reference (quoted by
Richard Guy previously in this thread) is "Prove that there exists at
least one n-persistent number for
each positive integer n."
Are you sure you are calculating these correctly?
