132 is the natural number following 131 and preceding 133.
[edit] In mathematics
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.
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]
But there is no number that, when added up to its own digits, adds up to 132, making it a self number. However, 132 is a Harshad number, divisible by the sum of its base 10 digits, as well as a Zuckerman number, divisible by the product of its base 10 digits.
[edit] In other fields
When counting in binary with fingers, expressing 132 as 0010000100 results in the isolation of the middle fingers of each hand, a gesture generally considered rude. The corresponding one-handed gesture is the representation of 4.
