Table of Contents for B4/Spin9/Spin(9)/PSp(8,R)  (data for the Spin(9) x PSp(8,R) block of Spin9)

TIIsubcells.txt : a listing of the wcells of the block and their partitioning by tau infinity invariants.
     This file includes information about the special orbits and W-reps attached to the wcells
     A line like tii[1,2] = {3,4} means that wcell elements #3 and #4 share the primitive ideal
     which in the Barbasch-Vogan-Joseph classification scheme corresponds to special orbit #1
     and basis element #2 in the corresponding special representation.
     (See B4/B4_TIIs.mpl for listing of the tau infinity invariants of B4.)
WCD.m : a Maple binary data file containing information on the wgraphs of the wcells of this block.
     Once read into Maple via the command
         read(WCD.m):
     a table WCD is loaded as well. If
         wcd := WCD[i]:
     then wcd is a list of datums for the i^th wcell and 
         wcd[1] = atlas index of the wcell
         wcd[2] = the cardinality of the wcell
         wcd[3] = a list of atlas block indices of the elements contained in the wcell
         wcd[4] = a list of datums for the individual scell elements. If
                     wced := wcd[4][k]:
                  then
                      wced[1] := internal cell index of the k^th wcell element
                      wced[2] := the tau invariant attached to this cell element
                      wced[3] : a list of the edge vertices of this cell element and
                                their edge multiplicities
blk.bin : binary output file obtained by applying the Atlas 'writeblock' command for this block
block.txt : text output file obtained by applying the Atlas 'block' command for this block
block_tiis.mpl :  a file detailing how the block decomposes into subsets with the same primitive ideal.
      A line like
           tii2blkelts[1,2] := {0,9,11)}
      means that the primitive ideal corresponding to special orbit #1 and basis element #2 of
      of the corresponding special representation of W is attached to block elements #0 , #9 and #11.
