theorem-h-orientation / closed-tilted-sheet

The closure of the tilted sheet carries no invariant (Theorem U section, item 7)

Closed route: just short of the reach of (V), the solutions that violate it carry no usable invariant.

One grid short of the window \((3, 2g + 1)\) the negation of (V) has exactly two solutions for the set of vertices of the rods’ type, a sheet advancing one chain label per cube, for every \(g\) from 3 to 7; on every shorter window the solutions are many and dense, and no Fourier coefficient, count or winding of the types is defined on all of them or constrained on those where it is defined; opening the transverse torus does not remove \(g\).
