Meanwhile, there is a brand of vacuum cleaner from Oz called the VAX and one of their models is the Ultrixx. I would of bought one, but we have a Dyson (upright, not round). Geoff. -- Geoffrey S.

That was the proof I had in mind, but you have to consider n even and odd, for example 1+3 is 4 but 2 has no match. -- A computer without Microsoft is like a chocolate cake without mustard.

And great accuracy is not needed. There is a relativistic effect that has to be accounted for in the case of communication satellites. -- A computer without Microsoft is like a chocolate cake without mustard.
