Name file [-T] [-Z] [-o] [-M] [-c]
file: bravais_TYP containing the space group R or the finite unimodular
The program is used to give crystallographic groups a name, i.e.
compute a string which is depends only on the crystallographic
class of the group R/G, and determines it uniquely.
CAUTION: the program assumes the translation lattice to be Z^n.
If called with -Z, the program assumes file to contain a finite unimodular
group G, and will output a name for the arithmetic class of G.
Otherwise, it will assume file to contain generators for the space group
R, and will output a name for the affine class of R.
Note that the first part of the name for a space group R is exactly the
name for the arithmetic class of the point group G of R.
-h : gives this help.
-T : output a matrix transforming the given group R/G into CARAT's
-o : output CARAT's representative for this affine/arithmetic class.
-Z : assume file to contain a finite unimodular group, more details
-M : give short Hermann-Mauguin symbols to describe a group
isomorphic to the given only (has an effect only if the
degree of R is two or three)
-c : gives the CARAT name as
"Q-class-name"-"Z-class-name"(-"name for the affine class")
