Positions and directions use fractional cell coordinates. Plane indices (hkl) are reciprocal-space normals; axis directions [uvw] are direct-space vectors. Blue = right-handed, red = left-handed.
An operation explorer, not a database of the 230 space groups. Selectable operations preserve the chosen cell metric; arbitrary combinations can generate a larger group or extra translations. d/e glides generate centering translations. Plane patches are schematic.
Coincident positions with different orientations are retained. Boundary copies are display-only.
