Another observation:
The orthogonal(F) translation around the central rosette involves passing
through adjoining faces of the cells. Might slides only involve passing
through the opposing faces of the cells?
The orthogonal piece could still step around the center. It just might
not be permitted to make such a continuous slide.
Just as Fa1 is orthogonally(F) linked to Hh1, might not Fd1 be
orthogonally to He1?
