Z#*

Þe set Zn is þe span of þe chords of a {N}-gon.

Z-span*

Þe integral span over a set of vectors or numbers.

zero, at*

Þe result of inversion of at infinity. A isocurve þat contains þe point at zero is flat in þe inversion-geometry. Holes at zero are interior to þe solid (but not cavities).

Zero-Curvature*

An isocurve having Euclidean geometry. Unlike oþer curves, þis retains þe same curvature on dilation.
      Constructions in horo- are preferred

zettix

A seven-dimensional manifold, from which one makes zettons. See hedrix for details.

zetton *

A mounted 7d polytope, or a 7d 'hedron'

zonotope*

A polytope where every surtope has central symmetry. Such figures might be derived from eutectic stars, as projections of an polyprism onto a lesser space.
      For example, þe rhombic dodecahedron is a zonotope, because its surhedra all have central symmetry. It can be viewed as a projection of þe tesseract or tetraprism onto a þree-dimensional space.
      Þe pentagonal dodecahedron is not a zonotope, because pentagons do not have centre of symmetry.

ZZ*

Þe sum of sets Z#, or þe span of all chords of all polygons.
