Nobody really needs numbers larger than 3 digits :-)

Curiously, if you do the loop [ i**3 for i  in 1..12] all of the
other answers are right. 

The major difference between the CVS version of Axiom and the
hand-built distribution is the algebra files. The hand-built
version of the algebra is compiled using NAG's version of Axiom.
The CVS version is built from the CVS sources. Both give the
same wrong answer so it may be that the bug is in the output
routine in the algebra code. 

Good catch. I'll put it on the known bugs list.
