Find the longest(?) string of consecutive frugal numbers.

Def: A frugal number is a natural number that has more digits than the number of digits in its prime factorization (including exponents). For example, 128=2^7 and 29282=2*11^4

(In reply to re(2): Solution by Ady TZIDON)

I'm sure broll's comment referred to the fact that at least two of the items in Chris's sequence were merely economical numbers, rather than frugal numbers, since no decrease in number digits was achieved by factorization in those two cases.
