In a cube or dodecahedron, you are correct, which is why neither will make a polywell. You need to truncate them; truncate them till the cuts meet in the center of the original edge. Then you have a cuboctahedron (if you start with a cube).charliem wrote:Have to admit that I still fail to see the meaning of that.KitemanSA wrote:... the main feature of a Polywell is that there are an even number of faces (pairs of opposite polarity) around eachvertex. The faces may be either all real, or half real and half virtual. But always two or more pairs of fields.

In a cube, cuboctahedron, or dodecahedron I can only picture 3 faces touching each corner (or vertex), neither 2 nor 4, so... what am I missing?

And what exactly means "of opposite polarity"?

May he have meantedgeinstead of vertex?

**This is a cuboctahedron.**

At each vertex (golden ball) there are 4 faces, two red and two yellow. Take the red to be the toroids and the yellows to be the triangular faces between and you have the classic WB6.

Clear now?
