• 65 is the international calling code for Singapore

• 65 is the smallest integer that can be expressed as a sum of two distinct positive squares in two (or more) ways, 65 = 8² + 1² = 7² + 4²

• 65 = 1⁵ + 2⁴ + 3³ + 4² + 5¹

• 65 is also a semiprime i.e. the product of two primes - 5 × 13

• 65 is the length of the hypotenuse of 4 different Pythagorean triangles, the lowest number to have more than 2: 65² = 16² + 63² = 33² + 56² = 39² + 52² = 25² + 60² .

• 65 is commonly used in names of many dishes of South India cuisine, for instance “Chicken 65”. 😋
