There are two crystallographic point groups with the property that no crystallographic point group has it as proper subgroup: O h and D 6h. This point group contains the following symmetry operations: E the identity operation. This reduces the number of independent structural variables from 12 (for an asymmetric, non-linear molecule containing six centers) to 3 and thus accelerates geometry optimizations. The letter is the rotational group and the subscript number after the letter indicates the order of the principal rotational axis (e.g. 15 demonstrates the excellent agreement between the experimental spectrum and simulation of the 1 A 1 ← 2 A 1 transition of the C 3v structure of La 3 O 4 .

A death rate is an estimate of the proportion of the population that dies during a specified period (Last 2001). The group has 8 irreducible representations. They not only contain a molecule's symmetry elements, but also give rise to a character table, which is a complete set of irreducible representations for a point group. There is a very important rule about group multiplication tables called rearrangement theorem, which is that every element will only appear once in each row or column. The first line tells you what the lookup in the internal table has produced for "68".This is the entry for space group 68, Origin Choice 1 ().This space group has the Schönflies symbol D2h^22, the Herman-Mauguin symbol Ccca and the Hall symbol "C 2 2 -1bc".
