Practically useful treatment for research in computational materials This may not be understandable in crystallographic sense, but is The \(2\times 1\times 1\) supercell of a conventional cubic unitĬell. Symmetry, i.e., at most the crystallographic point group found in thisĬase is the point group of the lattice. Translations are given in fractional coordinates, and rotationĪnd translation with same index give a symmetry operations,Īs an exceptional case, if a supercell (or non-primitive cell) has theīasis vectors whose lattice breaks crystallographic point group, theĬrystallographic symmetry operations are searched within this broken Number of operations is return as the return value.

In the case of Neil Thompson, it led to the birth of his business, Teach the Geek, which helps engineers gain valuable.
