Could'nt the 9th chevron be used as a function key? like a keyboards SHIFT button turning each symbol on the gate into a differant symbol, that would allow for more gates to be dialled.

Plus people keep refering to the "six point to pin point a location in space" the same can be done with eight. Imagine two four sided pyramid stuck together at the bases, it gives you a 3D diamond shape which can be used to pin point a location in space.
