T3D edge finding

Does anyone here know about the theory of edge finding?
Taking cones to be 30" on center, how many of 'em does
it take to find an edge to an accuracy of 6" which is of
course 1/5 the spacing of the cones?  Are the cones on a
hexagonal pattern?  Seems like they ought to be.  Can't 
imagine what would force them to be in another pattern
if they are basically round, as I understand them to be.

Thanks,
John B
