Let H denote a finite-dimensional Hopf algebra with antipode S over a field މ -. w We give a new proof of the fact, due to Oberst and Schneider Manuscripta Math. 8 Ž . x 1973 , 217᎐241 , that H is a symmetric algebra if and only if H is unimodular and S 2 is inner. If H is involutory and not sem

✦ Synopsis
Using the CREP system we show that matrix representations of representation-finite algebras can be transformed into normal forms consisting of (0, 1)-matrices.

We describe an algorithmic test, using the "standard polynomial identity" (and elementary computational commutative algebra), for determining whether or not a finitely presented associative algebra has an irreducible n-dimensional representation.
