icosahedron_geometry ( orientation='2n5' )

Possible orientations are 222, 222r, 2n5, n25, 2n3.

Orientation 222 has 2-fold symmetry along x, y, and z axes. Orientation 222r has 2-fold symmetry along x, y, and z axes, and rotated 90 degrees about z relative to 222.. Orientation 2n5 has 2-fold symmetry along x and 5-fold along z. Orientation 2n5r, 2n5 with 180 degree rotation about y. Orientation n25 has 2-fold symmetry along y and 5-fold along z. Orientation n25r, n25 with 180 degree rotation about x. Orientation 2n3 has 2-fold symmetry along x and 3-fold along z. Orientation 2n3r, 2n3 with 180 degree rotation about y.
