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(3): interesting side topic -- economical numbers -- transcription error compounded by broll)

That was the only typo and I've made the correction.
