Dear forum readers,

I have put a file `coco.grp' into the `/pub/incoming' directory on our

ftp server `ftp.math.rwth-aachen.de'. This file contains a GAP

function that will construct the primitive permutation representations

of simple groups of order less than a million, except for the

two-dimensional linear groups.

The information about these groups stems from the computer package

COCO (for computations with COherent COnfigurations) written by A. A.

Ivanov, I. Faradzev and M. Klin (UNIX port by A. Brouwer) and has been

translated into GAP-format.

Details about the new GAP function, including instructions on how to

install and use it, are contained in the short documentation file

`coco.tex' in the same directory `/pub/incoming'. You can run this

file through plain TeX to produce a printed description (2 pages).

Have fun, Heiko Thei{\ss}en
