Euclid space stratification: Fundamental domain & Wyckoff positions

Maximal Wyckoff positions: {a, b}
# - Ordinal, Label, Coo - general position coordinates, F - Stabilizer (isomorphic point group),
FEl - Stabilizer elements (exponents in the monomial in the generators {t, t_vc, S₄, Θ}), |F| - Stabilizer order,
|O| = |P_I|/|F| - Orbit order (number of orbit points per elementary cell
