module symmetry; % % ---------------------------------------------------------- % Symmetry Package % ---------------------------------------------------------- % % Author : Karin Gatermann % Konrad-Zuse-Zentrum fuer % Informationstechnik Berlin % Heilbronner Str. 10 % W-1000 Berlin 31 % Germany % Email: Gatermann@sc.ZIB-Berlin.de % % Version 1.0 9. December 1991 % % Abstract: % --------- % This program is an implementation of the algorithm % for computation of symmetry adapted bases from the % theory of linear representations of finite grous. % Projections for the computation of block diagonal form % of matrices are computed having the symmetry of a group. % % % REDUCE 3.4 is required. % % References: % ----------- % J.-P.
