Research
Symmetric Presentations Well, my research is in group theory which is a part of algebra. In particular, I study symmetric presentations. If you don't know what a group is then click here for a definition. If the reader seeks a representation of a group, then he should refer to the ATLAS of group representations which is maintained by R.A.Wilson and R.A.Parker. We shall give some presentations of ...

COHOMOLOGY OF 2-GROUPS
THE MOD-2 COHOMOLOGY OF 2-GROUPS On this web page we present the data from the first run of the computer calculation of the mod-2 cohomology of groups of order 8, 16, 32 and 64. to see the results of the second run click here.. All of the calculations were run using the MAGMA computer algebra system. The groups are indexed by their Hall-Senior Numbers. State of the Calculation The first run was ...

Parallel GAP/MPI (ParGAP/MPI)
Parallel GAP/MPI (ParGAP/MPI), a share package for GAP This package works only under UNIX. (Cygwin is an option on Windows, but you will have to port it, then.) The most recent version of this package can always be found in the ParGAP ftp directory. You can also find ParGAP/MPI at the web page for GAP share packages. A good introduction to ParGAP is available as a preprint in either gzipped ...

Trinomials with interesting Galois groups
Trinomials axn+bx+c with interesting Galois groups In 1969 Trinks discovered that the irreducible trinomial x7 - 7 x + 3, factored modulo small primes (other than the primes 3 and 7 dividing its discriminant 218), always yielded polynomials of degrees 7, 4+2+1, 3+3+1, or 2+2+1+1+1. This suggested that the trinomial had Galois group G168, the simple group of order 168 consisting of the invertible ...
