Abstract
We compute generators and relations for the basic algebra of a non-semisimple singular block of the restricted enveloping algebra of over an algebraically closed field of characteristic . Working directly with the basic algebra we compute its centre and the internal degree zero part of its first Hochschild cohomology, and show its Verma modules are Koszul.
