COMMENTS
Sequence is infinite with trivial terms of the form k*10^r, k = 1 to 9. Conjecture: There are finitely many nontrivial terms (not of the form k*10^r). All the two-digit terms are the same as those of A085133.
EXAMPLE
243 is a term as 243, 432 and 324 all are terms of A002473. 243 = 3^5, 432 = 2^4*3^3, 324 = 2^2*3^4.
