corrected dekany movies

Thanks to George, I was able to correct the coordinates of the dekany to:

(2,0,0,-2/sqrt(5))
(0,2,0,-2/sqrt(5))
(0,0,2,-2/sqrt(5))
(-2,0,0,-2/sqrt(5))
(0,-2,0,-2/sqrt(5))
(0,0,-2,-2/sqrt(5))
(-1,1,1,3/sqrt(5))
(1,-1,1,3/sqrt(5))
(1,1,-1,3/sqrt(5))
(-1,-1,-1,3/sqrt(5))

I've corrected the movies at http://www.egroups.com/files/tuning/perlich/:

dekany2_4d.mpg [the 2)5 dekany]

dekany_4d.mpg [the 3)5 dekany]

They look better!

Next, I'll try a version that starts with the nested pentagram
representation.
