55 (fifty-five) is the natural number following 54 and preceding 56.

Fifty-five has the interesting property that it is the 10th Fibonacci number and the sum of the numbers 1 to 10.

It is a heptagonal number, a centered nonagonal number, and a triangular number (the sum of the numbers 1 to 10) and a square pyramidal number (the sum of the squares of the integers 1 to 5). It is also a Fibonacci number (the largest Fibonacci number to also be a triangular number) and a Kaprekar number.

55 is a semiprime, being the product of 5 and 11 and it is the 2nd member of the (5.q) semiprime family. 55 is one of only two integers with an aliquot sum of 17 (the other being 39). 55 has an aliquot sequence of 4 members: (55, 17, 1, 0).

I was actually obsessed with 55 for a while when I was little, partially because it was the speed limit back then so I saw it a lot, partially because I liked someone who was 55 inches tall and didn't know how to react, so I just obsessed about the number.

^Aw. That's cute!

Heh, thanks. Even as an adult, I don't like talking about my silly little obsessions from when I was a kid, since my brothers teased me mercilessly about them.

Well, I've moved on to 56, now.

But thank you all for your input.

Haven, that pun was so mean.

Sorry, next time I'll try a different mode.

Dividing the octave into fifty-five equal parts yields a closed-loop variant on the 1/6-comma meantone scale.
