Yes, makes sense. There'll be more corners and therefore a smaller 
volume for the hypersphere. Interesting. But for some reason I feel I've 
got other, much more down to earth, facts of life entangled with me.

For instance, when I boot and out of blue, nothing comes up on the 
screen, but computer lights indicate normal activities, is it the fault of:

1.  Dell OptiPlex 7050 micro computer's GPU?
2.  its displayport receptacle?
3.  the displayport plug of the display cable?
4.  the wire part of the display cable?
5.  the DVI plug at the other end of the display cable?
6.  the DVI receptacle at the back of the monitor?
7.  Something inside the monitor burnt perhaps?
8.  Something inside the 7050 burnt perhaps?

The only suggestion Relf ever had in his life for _any_ computer issue 
was, "Get a new display cable."  So ...

9.  Should I order a new display cable?

I've thrown away all damaged monitors which worked but the display was 
messy. So I have nothing to change the present monitor with to see if 
problem is with monitor's end of the system. All my other computers are 
nicely stowed away after hours of work, as of last night. So ...

10. Should I go fuck it up again and get them into a mess like they were 
before I carefully carried them away and placed them there away from 
cats, nice and neat, just to see monitor works with them correctly?

Things of this nature. Hehe :)

Doesn't go well with n-dimensional hyperstuff.
