**Icosahedral symmetry**— A Soccer ball, a common example of a spherical truncated icosahedron, has full icosahedral symmetry. A regular icosahedron has 60 rotational (or orientation preserving) symmetries, and a symmetry order of 120 including transformations that… …112

**CPT symmetry**— CPT theorem redirects here. For the album by Greydon Square, see The C.P.T. Theorem (album). CPT symmetry is a fundamental symmetry of physical laws under transformations that involve the inversions of charge, parity, and time simultaneously.… …114

**Translational symmetry**— In geometry, a translation slides an object by a vector a: Ta(p) = p + a.In physics and mathematics, continuous translational symmetry is the invariance of a system of equations under any translation. Discrete translational symmetry is invariance …115

**Tetrahedral symmetry**— A regular tetrahedron has 12 rotational (or orientation preserving) symmetries, and a total of 24 symmetries including transformations that combine a reflection and a rotation.The group of symmetries that includes reflections is isomorphic to S 4 …117

**C-symmetry**— In physics, C symmetry means the symmetry of physical laws under a charge conjugation transformation. Electromagnetism, gravity and the strong interaction all obey C symmetry, but weak interactions violate C symmetry. Contents 1 Charge reversal… …118

**Dihedral symmetry in three dimensions**— This article deals with three infinite sequences of point groups in three dimensions which have a symmetry group that as abstract group is a dihedral group Dihn ( n ≥ 2 ). See also point groups in two dimensions. Chiral: Dn (22n) of… …120

**T-symmetry**— is the symmetry of physical laws under a time reversal transformation mdash;: T: t mapsto t.Although in restricted contexts one may find this symmetry, the universe itself does not show symmetry under time reversal. This is due to the uncertainty …
