Number of rods connected to a sphere.

For "pure Geomag" models (with 1/2" spheres) this is a number between 1 and 14.

For an illustration of the maximum "pure Geomag" valency, see The 14 Puzzle.

## To Do Edit

- What are the maximum valencies for the related systems?

- - Supermag with 1/2" spheres (24)
- - Supermag with 3/8" spheres (?)
- - Supermag with 5/8" sphere (30)

- - Geomag with 5/8", 3/4", 7/8" and 1" spheres.

- - Rogers Connection with 5/8" spheres (12)

- What is the minimum angle between two rods for each of these cases?
