== Blocks ==

Unless stated otherwise, blocks of a finite group <math>G</math> will be indecomposable two-sided ideals of <math>kG</math>. In some situations it will be the corresponding block of <math>\mathcal{O}G</math>.

<math>B_0(A)</math> will denote the principal block of an algebra <math>A</math>. However we often use the notation of [http://www.math.rwth-aachen.de/~MOC/decomposition/| GAP] to label blocks of certain groups, where the principal block is usually labelled <math>B_1(kG)</math>.
