16
The first two digits of this number spell "16," which is a fellow power of twoooo! It's actually a factor of this number. Six times, in fact!
777
OK here's the part that really sticks out. The thousands, ten thousands, and hundred thousands digits of this number are all seven! We really hit the jackpot there. How lucky is it that such a mathematically significant number contains this sequence of digits? It's functional, and fashionable.
Haha, function? Like an exponential function? That pun may be a bit of a stretch. I really like exponents though.
216
The final grouping of digits matches another perfect cube, 216. It also looks kinda like 256, which is the cube root of the number this article is about. I like that number.
