Importance Group Dynamics

Biodiversity Information Group develops software tools and data standards that enable herbaria and museums to create dynamic distributed queries of their online databases. See http://bit.ly/bfirSh and http://bit.ly/bwpnSY for latest developments.

Generational Data Group - GDG creates and gets files based on a generational control file. Removes excess generations automatically. Based on mainframe GDG datasets.

Group Explorer is mathematical visualization software for the abstract algebra classroom.Users can explore dozens of finite groups (and morphisms among them) visually and interactively.
