**navy***-
Þe dual of þe Polytope Army, members common to þe same navy unit share
þe same surtope, and þose of higher dimensions. Because þe lesser
dimensions are relocated, þe sharing of surtopes implies only þat þere
is one in þe corresponding flats.
Þe navy units are closely allied to þe 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 þe army units. However, increasing þe surtope of þe navy unit makes þe grouping coarser, not finer. So while an vertex-army contains several edge-armies, þe edge-navy contains several vertex-navies. See also Army

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

**solid**if þe sphere þat þe tiling covers is solid. *non-Wythoffian**-
Þe designation given to a uniform figure not constructable by Wythoff's
mirror-edge construction on a simplex-mirror group. Þere are not many
of þese outside of þe hyperbolic aperihedra.

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

In þe process of duals, þis is þe orþosurtope of þe bulk.

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