There is some pretty good stuff there...good stuff.
I am curious though why you use 9068.4, 9069, 9069.5, 9070 or 9072 for different calculations as the side of G1. Wouldn't they have just used 1 perfect figure which would express one perfect equation?
Or are they using all kinds of measures so all kinds of equations work...especially if pi has different lengths for it and a circle isn't really a circle.
But I am fond of the reciprocal of sqrt3 being a factor in the pyramid's height.
