Support: Project II.6 in the transregional collaborative research centre SFB-TRR 195 'Symbolic Tools in Mathematics and their Application' of the German DFG

Overview:
Generation of various algebras, including group algebras of finitely presented groups in the Letterplace ring. FPA stands for finitely presented algebra.
