...Now,
examine the impact on photons movement and moment. The z-Symmetry has no impact
on it : there is no "antiphoton". As all the charges of the photon are zero
a does not change it. It is identical to its antiparticle.
...The
coadjoint action of orthochron components modifies the movement and the moment
of the photon, but keep unchanged its energy. See figure (408)

on photon's movement
and moment.

The coadjoint action
of antichron elements on photon's movement au moment reverses its energy
: it travels backwards in time.
...The
antichron elements of the group acts on the momentum through coadjoint action.
Such elements transform the normal photon, travelling forward in time un the
z = 0 plan of the fold Finto a movement in the corresponding plane
of the fold F*. This photon travels backwards in time. Its energy is negative.
About the contents
of the two folds.
They can be summarized
in the following tables.
