  [33X[0;0YInputs  a  meataxe  module  [22XM[122X  over  the  field of [22Xp[122X elements and returns an
  FpG-module  DM.  The two modules are related mathematically by the existence
  of  a  short  exact  sequence  [22XDM  ⟶  FM ⟶ M[122X with [22XFM[122X a free module. Thus the
  homological properties of [22XDM[122X are equal to those of [22XM[122X with a dimension shift.[133X
