To run
these old DOS programs in the latest versions of Windows ( they may or may not run on older
Windows versions ) you can use the DOSBox program:

Install it.

Dowload a
zipped DOS program listed below. In diskdrive X create a file
YYYY (Choose any diskdrive X and file YYYY you want.) Then

extract (unzip) the zipped file into the file YYYY in diskdrive X.

Run DOSBox.

Type
mount c: X:\YYYY (where X and YYYY are the diskdrive and file you
chose)

press return

Type c:

press return

Type Name of
the start program

I have not
checked every instance, but it seems one can no longer printout
anything.

**SPACE GROUP MULTIPLICATION**

A little program to which gives the product of
the multiplication of two space group elements.

**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). A**45**,
801-802.
(an old DOS program.)

listed on the right and the corresponding double coset representative on the left. Of each tensor pair, the second tensor is obtained from the first by applying the corresponding double coset representative. See publication #55 "Physical property tensors and tensor pairs in crystals" by S.Y. Litvin & D.B. Litvin, Acta Cryst. A46 711-713.

**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.)

Note: To end the introduction, press esc. Then type icoprog, press return and go back to the main menu.

Note: In viewing the icosohedron, most choices correspond to defunct graphics cards. I could view the icosahedron using choices "E" and "O". I don't know what will work for you. Again, typing icoprog and pressing return will take you back to the main menu.

**RANK 0, 1, 2, AND 3 MAGNETIC AND
NON-MAGNETIC PHYSICAL-PROPERTY TENSORS*
**The form of 36 rank 0, 1, 2, and 3
magnetic and non-magnetic physical-property tensors invarinat under
each of the 236 subgroups of D6h1' and each of the 420 subgroups of
Oh1' are tabulated. See publications #57 "Rank 0, 1, 2, and 3
