  [33X[0;0YInputs  a  pure  cubical  complex  (or  cubical  complex)  [22XK[122X and returns the
  corresponding  regular  CW-complex. If a positive integer [22Xn[122X is entered as an
  optional second argument, then just the [22Xn[122X-skeleton of [22XK[122X is returned.[133X

  [33X[1;0Y[29X[2XCriticalCellsOfRegularCWComplex[102X( [3XY[103X, [3Xn[103X ) [32X function[133X
  
  [33X[0;0YInputs  a  regular  CW-complex  [22XY[122X  and  returns the critical cells of [22XY[122X with
  respect  to  some  discrete  vector  field.  If  [22XY[122X does not initially have a
  discrete vector field then one is constructed.[133X
  
  [33X[0;0YIf  a  positive integer [22Xn[122X is given as a second optional input, then just the
  critical cells in dimensions up to and including [22Xn[122X are returned.[133X
  
  [33X[0;0YThe  function  [22XCriticalCellsOfRegularCWComplex(Y)[122X works by homotopy reducing
  cells     starting     at     the     top     dimension.     The    function
  [22XCriticalCellsOfRegularCWComplex(Y,n)[122X  works  by  homotopy  coreducing  cells
  starting  at  dimension 0. The two methods may well return different numbers
  of cells.[133X

  CW-complex  W whose cells correspond to the critical cells of [22XY[122X with respect
  to  some  discrete  vector  field.  If  [22XY[122X does not initially have a discrete

  [33X[0;0YInputs a regular CW-complex [22XY[122X and, optionally, the number of some 0-cell. It
  returns  the  fundamental  group  of  [22XY[122X  based at the 0-cell [22Xn[122X. The group is
  returned as a finitely presented group. If [22Xn[122X is not specified then it is set
  [22Xn=1[122X.  The  algorithm  requires  a  discrete vector field on [22XY[122X. If [22XY[122X does not
  initially have a discrete vector field then one is constructed.[133X
