Complete this sequence:

_, _, _, _, _, _, _, _, _, 3888, 42768, 513216, 667188, 934632,
141948, 2271168, 3869856, 6965748, 132349212, 264698424, ...

Yup, I'd like terms 1-9.

Bonus points for the mathmos: give an expression for how quickly this
series grows: how many digits would you expect the 1000th, 10000th,
100000th, and 1000000th terms to have?

We are no longer hunters and nomads. No longer awed and frightened, as we have
gained some understanding of the world in which we live. As such, we can cast
aside childish remnants from the dawn of our civilization.
