This **work phase
(1989-90)** is based on the 5-dimensional Hyper-cube, a structure
build from a set of eighty lines. A subset of twenty lines,
containing four lines from each "dimensional-direction" are chosen
from this structure. Each "dimensional-direction" consists therefore
of four parallel lines, represented by three thin lines and one
thick line (drawn in a given 5-dimensional rotation). The work
P-452-A, shows the ten possible combinatorial 2-D projections of
such a group of twenty lines at a given rotation.
