In mathematics

This number in base 10 can be expressed in operations using its own digits in at least two different ways. One is as a sum-product number,

135 = (1 + 3 + 5)(1 \times 3 \times 5)

(1 and 144 share this property) and the other is as the sum of consecutive powers of its digits:

135 = 1^1 + 3^2 + 5^3

(175, 518, and 598 also have this property).

135 is a Harshad number.

There are a total of 135 primes between 1,000 and 2,000.

135 = 11 n^2 + 11 n + 3 for n = 3. This polynomial plays an essential role in Ap ry's proof that \zeta(2) is irrational.
