Davis Smith: I have tested this with a few other expomophic sequences and my pari here will generate the terms, in order, so long as the first term in the sequence is equal to the base of that sequence. There are some interesting cases, such as 99, which generates one in base 100 (99, 9899,479899,48479899, and so on).
