# 132: interesting findings from a random search on Wikipedia

Just now, I was browsing Wikipedia and made a random search by typing '132' into the search box. I don't know why I did this. Maybe I was just trying to figure out whether there existed someone who would bother to write something about this boring number.

132 is the sixth Catalan number. It is a pronic number, the product of 11 and 12. As it has 12 divisors total, 132 is a refactorable number.

Well I admit I cannot understand any of the names of number (Catalan, pronic and refactorable). They are, obviously, completely out of my vocabulary. But the point is - why would someone spend hours, maybe tens of hours, to write the features of a number online? They are so interesting.

If you take the sum of all 2-digit numbers you can make from 132, you get 132: 12 + 13 + 21 + 23 + 31 + 32 = 132. 132 is the smallest number with this property,[1] which is shared by 264, 396 and 35964 (see digit-reassembly number).

Seems that that post was written by some mathematician whose field was number theory. Well, not only interesting enough, but also very boring.

Then I scrolled down and found something like this:

I was shocked. And finally realised how boring some scientists could be.

Well, they were not SO boring. On the Chinese Wikipedia page of '132' I saw a funny fact about 132 (translation made by myself):

When written in binary, 132 is 0010000100. If you use your fingers to represent binary numbers, you will get an indelicate gesture.

If you have a try, like what I did, you'll get this:

So mathematicians are not as boring as we think, are they?
