Unsolved Problem 28:
The number 3 can be written as 1^3+1^3+1^3 and also as
4^3+4^3+(-5)^3. Is there any other way of expressing 3
as the sum of three (positive or negative) cubes?

Expressing 3 as the Sum of Three Cubes
Each week, for your edification, we publish a well-known
unsolved mathematics problem. These postings are intended
to inform you of some of the difficult, yet
interesting, problems that mathematicians
are investigating. We do not suggest that you tackle these problems,
since mathematicians have been unsuccessfully working on these
problems for many years.
