COMMENTS

Numbers k such that fract(e^k) > 1(1/k), where fract(x) = xfloor(x).
The next such number must be greater than 100000.


LINKS

Table of n, a(n) for n=1..7.


EXAMPLE

a(2)=8, since fract(e^8) = 0.957987... >0.875 = 1(1/8), but fract(e^k) = 0.389..., 0.085..., 0.598..., 0.413..., 0.428..., 0.633... for 2<=k<=7 which all are less than 1(1/k).
