the empty gongyl is the glome, which is the 4d-equivalent of the sphere, when it has no surface the object is non-existence and reverted to nill-space which is void and empty.
simular with the pentaspace "duocylinder" (alkaline hasn't updated the glossary yet) without a surface it, as well as the duocircle, reverts to nill-space.
As said nill-space is empty and void, so what is there to understand
Don't smell yourself
and don't get nillified by arsenic poisoning :twisted: (
can this kind of suicide be done, probably you'll just double in strength
)
As derived elsewhere the glome is isomorphic to a 3d filled beam (π,π,2&pi) (or perhaps better said filled double-cube, because one of its side is double the other two side) which is open at one (square) end.
The duocircle is isomorphic to the 2d filled square (2π,2π), so the pentaspace duocylinder a filled beam based on that square the third direction is of not specified length, so you could make it a filled cube.
All these objects are well understood. :wink:
