36 (thirty-six) is the natural number following 35 and preceding 37.

In mathematics

36 the square of 6 as well as a triangular number, making it a square triangular number, the smallest square triangular number other than 1 and also the only triangular number whose square root is also a triangular number.

It is also a 13-gonal number.

It is the smallest number n with exactly 8 solutions to the equation φ(x) = n. Being the smallest number with exactly 9 divisors, 36 is a highly composite number. Adding up some subsets of its divisors (e.g., 6, 12 and 18) gives 36, hence 36 is a semiperfect number.

This number is the sum of a twin prime (17 + 19), and the sum of the cubes of the first three integers.

36 is the number of degrees in the interior angle of each tip of a regular pentagram.

Since it is possible to find sequences of 36 consecutive integers such that each inner member shares a factor with either the first or the last member, 36 is an Erdős–Woods number.

Because 36² + 1 = 1297, a prime, which is obviously more than 2 × 36, 36 is a Størmer number.

The sum of the integers from 1 to 36 is 666 (see number of the beast).
