Polytopes & their
Incidence Matrices

 

Square dance is an other hobby of mine.
- This picture shows a polyhedral mobile with pairs of regular ones dancing (in square dance formation) underneath a cubical truss, which in turn was chosen as a 3 dimensional version of the square dance symbol i.e. two interlinking squares.

allowance will not be a must within this site. Even so, the reduction marks (±) in tree-lists (as in the site map above) would not work, nor would some few interactive VRMLs.
