11. The preceding discussion assumes the degenerate hyperplane is not in the arrangement. 12. Geometrically, this amounts to including shears in a hyperplane . 13. The margin between the hyperplane and the clouds is maximal. 14. Cayley-Klein Voronoi diagrams are affine diagrams with linear hyperplane bisectors. 15. Then there is a closed hyperplane in containing with " } }. 16. The hyperplane separation theorem is due to Hermann Minkowski. 17. Both sets could have points located on the hyperplane . 18. A reflection in a hyperplane has the effect of interchanging the two eigenspaces. 19. The hyperplane intersections generate cyclotruncated 5-cell honeycomb divisions on each hyperplane. 20. The hyperplane intersections generate cyclotruncated 5-cell honeycomb divisions on each hyperplane .
