InfoCountAlg
An info class InfoCountAlg
for this package is provided. Depending on the chosen level the function NumberOfClassTwoAlgebras
(2.2-1) gives information on the progress of the computation.
The default value is 2.
If the info class is chosen to be 0 no intermediate data is printed.
gap> SetInfoLevel(InfoCountAlg,0); gap> NumberOfClassTwoAlgebras(2,Kronecker); [ q-(q-0,2)+5, 3*q-(q-0,2)+6 ]
If the info class is chosen to be 1 it is just printed at what stage the algorithm is.
gap> SetInfoLevel(InfoCountAlg,1); gap> NumberOfClassTwoAlgebras(2,Kronecker); #I Determine exceptional chars #I Determine or catch extension dimensions #I Determine jnf types in GL #I Determine equations for 4 types #I Apply action to 4 types #I Determine fixed points in dims: [ 1 .. 2 ] #I Determine PORC poly in dims: [ 1 .. 2 ] #I Simplify PORC polys [ q-(q-0,2)+5, 3*q-(q-0,2)+6 ]
If the info class is chosen to be 2 details are given while the types of matrices are considered. Note that not all types are considered. There are symmetries used such that some types are skipped.
