1729

(this number and fact were submitted by @amorbidobsessionwithbeauty)

1729 is the first non-trivial taxicab number, and is also known as the ramanujan-hardy number.

A taxicab number is one that can be expressed as the sum of cubes of two positive integers in n distinct ways. The first (trivial) solution is 2 (1³+1³). In case of 1729, which is the second taxicab number:

Ta(2)=1³+12³=9³+10³=1729

Similarly,

Ta(3)=167³+436³=228³+423³=255³+414³

Thus, for Ta(n), there must be n different ways to represent it as a sum of cubes of 2 positive integers.
