Depending on context, this could mean one of two things:

1) 1,729, also known as the "Taxicab Number", i.e. the smallest number that is the sum of two cubes in two different ways, aside from the trivial case of 1.

2) exp(pi*sqrt(163)) = 262,537,412,640,768,743.99999999999925... - the result of an April Fool's Day joke that claimed this number is an integer (which it is not).
