the multiplication of two space group elements. (an old DOS program).

PROPERTIES OF THE 32 POINT GROUPS*
This program gives the notation, elements, subgroups, centralizers,
normalizers, normal subgroups, and coset and double coset
decompositions
of the 32 crystallographic point groups. See publication #54:
"The
coset and double coset decompositions of the 32 point groups," by V.
Janovec,
E. Dvorakova, T.R. Wike, and D.B. Litvin, Acta Cryst. (1989). A45,
801-802.
(an old DOS program.)

"print out" is requested.] [
Output of this program can also be generated by the downloadable
program "Properties of the Magnetic Point Groups" below.)
ICOSAHEDRAL POINT GROUPS*
Permutations of the vertices of an icosahedron
under the action of the elements of the icosahedral point groups, the
icosahedral
point groups' multiplication tables, subgroups, sets of conjugate
subgroups,
centralizers and normalizers of arbitrary subsets and coset and double
coset decompositions. See publication #56: "The Icosahedral Point
Groups"
by D.B. Litvin, Acta Cryst. (1991) A47, 70-73. (an old DOS program, now
given as three separate files containing a drawing of an icosahedron
with
indexed vertices, an intro file, and program file.)
