**navy***-
The dual of the Polytope Army, members common to the same navy unit share
the same surtope, and those of higher dimensions. Because the lesser
dimensions are relocated, the sharing of surtopes implies only that there
is one in the corresponding flats.
The navy units are closely allied to the process of stellation.

Unit group leader Stellation name ------------------------------------+-------------------------------- face-navy fleet admiral | edge-navy stellated margin-navy ship commodore | surhedron-navy great 2margin-navy boat coxwain | surchoron-navy grand

Navy units form sets etc as does the army units. However, increasing the surtope of the navy unit makes the grouping coarser, not finer. So while an vertex-army contains several edge-armies, the edge-navy contains several vertex-navies. See also Army

*node**- The second-series name for an vertex: see sesquitope
**noid***-
Coxeter's name for any spheric tiling that in parabolic space becomes
flat. Typically, these involve a 2 in the Schlafli symbol, and marks
on only one side of it, eg {;2,p} = hosohedra, {p,2} = dihedra.
A noid is

**solid**if the sphere that the tiling covers is solid. *non-Wythoffian**-
The designation given to a uniform figure not constructable by Wythoff's
mirror-edge construction on a simplex-mirror group. There are not many
of these outside of the hyperbolic aperihedra.

See also snub(Coxeter) and snub(Wythoff) *nullitope **- The notional -1 edge, that arises as the dual of the solid substance of a polytope. This is normally residing at infinity, and gives rise to "spiritual" connections because of this. It is part of the surtope equation.
**nulloid ***-
A calculation fiction introduced to simplify a number of calculations. The
surtope is reckoned as having d-1, and residing at a vast distance.

In the process of duals, this is the orthosurtope of the bulk.

A single nulloid is reckoned in the tegum and pyramid products.
