Matrix Groups: Week 10 Update

We are now at a stage where the only thing left to do is to produce an Applet that will draw the Hasse diagram for a given set of subgroups. Over the previous weeks I have been producing the algorithm that works out all the subgroups for a given group, and also all the links between the subgroups. These links are stored in an n-by-n array, where n is the total number of subgroups.

So we have the list of subgroups, an array denoting the links between subgroups, and also the dimensions of the Hasse diagram. The Applet you see below is now nearly finished — all the remaining work will concentrate on writing the code that draws the Hasse diagram. This is what will be implemented in the next few weeks.
