+
Built before the advent of panels, this is a satisfying model. All of the internal supporting pyramids make solid contact with their outer shell spheres, and you can easily handle the model when complete.
   
* Keep the spheres magnetically neutral by [[Balanced polarity|balancing the polarities around each vertex]] for maximum strength.
+
For the Geomag purist, there is a cheat here: the main vertices are built with 5/8" spheres so that the rods can sit squarely on the nodes. (from a precursor to Geomag called Roger's Connection). The regular Geomag balls are only 1/2" diameter, so this model looks chunky, and feels like a cannonball.

Vital statistics: 60 large vertices, 42 inner vertices, 300 geomag bars in these colors: 120 yellow bars for the outer shell, 120 silver bars for square pyramids, 60 red bars for pentagonal support.
