Mathematically, what's the neatest thing about your racing number?

Mine is the lowest number whose neighbors have the same number of divisors as it. (it has 4 divisors , and so do x+1 and x-1, where it is x ) It’s also a Fibonacci number and a Markov number, among other things that are either just boring or too complex to explain with words. I’m going to let you figure out what number it is, although I’m sure you could figure that out just by Googling.

Type your number into Wikipedia and you’ll get pretty much all there is to know about it.

Mine is an imaginary number.

i read your whole post and all i hear is fart noises

fibonacci markov?

who dat?

i sucked at math in school and clearly dropped out to soon

luckily i have a steady hand and a knack for technical drawings or i might be unemployable

Mine is the answer to life, the universe and everything:

Mine is the name of a Green Jellÿ album.

and is half of THE DEVIL’S NUMBER!!

42 degrees is the angle at which a rainbow appears, so I can’t disagree there!

1 is the only positive number that is neither prime nor composite. It’s also arguably the only number that matters, as every other integer can be described as the sum of a stri ng of ones.

333 actually doesn’t have any majorly interesting properties, although 331 is the sum of five consecutive primes, as well as it is a prime itself. So, you’re close to a cool one!

42 degrees is the angle at which a rainbow appears, so there’s that!

Because I married a mathematician, our autocross numbers for his car, 13 and 31, are Mersenne Primes. This means they also happen to fit the pattern 2^n - 1.

I use #27 on mine. Mathematically speaking, I’d say it’s at least mildly interesting for being a perfect cube (3^3) and equaling the sum of integers between its digits (2+3+4+5+6+7 = 27). The real reason I chose it, however, is that Weird Al has deemed it a “funny number” and made use of it in many of his songs and music videos.
