I just watched the Numberphile video about Apocalyptic Numbers.
An apocalyptic number is a power of two whose decimal
representation contains the digits "666". I nodded along: of course, Christian folks would get interested about numbers
that contain "666". But then I thought about it some more and wondered: *Why would those Christian people care about powers of two so much?*
If you're going to look for "666" in some numbers, why not Fibonacci numbers or powers of three or what-have-you?

Who *should* care about powers of two? Computer programmers, that's who.
But not all computer programmers are Christian; not all care about 666.

I think we should instead focus on Leet numbers, powers of two that contain "1337". Yes, I just made up the term "Leet numbers," but I'm sticking to it.

The first Leet number is 2^{394} = 403476543451079467**1337**3737062547060536401653012956617387979052445947619094013143666088208645002153616185987062074179584.

The first Eleet number (containing "31337") is 2^{454} = 465176783549188409951567237048322901986330470839883558580153727475609144392574670928762272456808681958888013828010353877462145042**31337**984.

Now that *that's* settled, I guess I should come up with 15 minutes' worth of things to say about that and then get in touch with the Computerphile people to make a video.
