Beaten by both of you!

I wrote done all the cubes up to 10 and got one wrong (which was 6 so it rather scuttled me) - and didn't quite get round to writing a program to work it out for me.

Must remember that years of computing have sapped my powers of mental arithmetic!

Points shared between the two of you, I think (unless you fancy having a shoot-out with 42 as the target Smile | :) ).

(Edit)Computer has found some more:

2 = -24^3(-13824) + -47^3(-103823) + 49^3(117649)
2 = -54^3(-157464) + -161^3(-4173281) + 163^3(4330747)
2 = -96^3(-884736) + 385^3(57066625) + -383^3(-56181887)
2 = -150^3(-3375000) + 751^3(423564751) + -749^3(-420189749)

Now we just need to work out why it's a remotely useful thing to know about a number ...
