Take the lexicographically earliest sequence, subject to the rules that the leftmost digit must be replaced by a nonzero digit, the other digits by any digit.
It is not known if the sequence is infinite.
The sequence is finite with last term a(17115) = 3377464733, see links for illustration. - Reinhard Zumkeller, Apr 20 2011
Zumkeller's demonstration of finiteness is false if some other leading 0 rather than the immediate leading 0 can be replaced, otherwise a(17116) = 203377464733 (cf. also A059498). - Sean A. Irvine, Sep 25 2022
