That's what I like to see, given my:

I guess my code could get there in about a day if I ran it on a faster
machine. This box has a 1.66 GHz low power AMD embedded processor and
took just under 4 hours for the above. I don't really see a way of
getting any significant speed-ups over my simple code, as it's
inherently a digit-by-digit operation.
