Symmetric functions in MAGMA
(2007)
- We describe two algorithms which were used to implement symmetric functions in the computer algebra system MAGMA. We describe one algorithm based on the work of Lascoux and Schutzenberger for the multiplication. One further algorithm is given for the computation of plethysms.

Integral point sets over Z_n^m
(2007)
- There are many papers studying properties of point sets in the Euclidean space or on integer grids, with pairwise integral or rational distances. In this article we consider the distances or coordinates of the point sets which instead of being integers are elements of Z_n, and study the properties of the resulting combinatorial structures.
