Name in the International Tables for Crystallography
P2/m (Primitive monoclinic Bravais-lattice symmetry group) P
10 2/m
Crystal system
Monoclinic 2/m
Asymm
0 ≤ x ≤ 1/2 and 0 ≤ y ≤ 1/2 and 0 ≤ z ≤ 1

Translation
 
Symmetry (atomic coordinates)
X, Y, Z; X, -Y, Z; -X, Y, -Z; -X, -Y, -Z
Crystal symmetry
Is centrosymmetric because it has -x,-y,-z in its symmetry.
