On the blocks of [Sfr ] over a field of characteristic three
Published online by Cambridge University Press: 26 July 2002
Abstract
In [16] and [17], Tan looks at the principal blocks of the symmetric groups [Sfr ]9, [Sfr ]10, [Sfr ]11, [Sfr ]12 over a field of characteristic three, and highlights the contrast with blocks of small abelian defect. Here we continue by determining the Ext-quivers of the blocks of [Sfr ]13 over the same field; this in particular provides examples of a [4:1]-pair and a [3:2]-pair with non-abelian defect.
