摘要
A number is said to be economical if the prime power factorisation of can be written with no more digits than itself. We show that under a plausible hypothesis, related to the twin prime conjecture, there are arbitrarily long sequences of consecutive economial numbers, and exhibit such a sequence of length 9.
