**1,729** is the “taxicab number”; the smallest number that is the sum of two cubes in two different ways: 1000+729 = 1728+1

**17,290** is 10 times the taxicab number.

**36,100** is the sum of the first 19 cubes.

**50,021** is a prime number, meaning that it has no factors except one and itself.

**109,376** is an automorphic number; if you multiply it by itself any number of times, the same six digits remain at the end.
