<P/>
 The <Emph>degree</Emph> of a representation is also known as the <Emph>dimension</Emph>.
 The <Emph>level</Emph> of the congruent representation determined by the pair <Math>(S,T)</Math> is equal to the order of <Math>T</Math>.
<P/>
 We assign to each representation a <Emph>name</Emph> according to the conventions of <Cite Key="NW76"/>.
