int gen_oh ( int code, double a, double b, double v, double *x, 
  double *y, double *z, double *w )

//****************************************************************************80
//
//  Purpose:
//
//    GEN_OH generates points under OH symmetry.
//
//  Discussion:
//
//    Given a point on a sphere, specified by A and B, this routine generates
//    all the equivalent points under OH symmetry, making grid points with
//    weight V.
//
//    The variable NUM is increased by the number of different points
//    generated.
//
//    Depending on CODE, there are from 6 to 48 different but equivalent
//    points that are generated:
//
//      CODE=1:   (0,0,1) etc            (  6 points)
//      CODE=2:   (0,A,A) etc, A=1/sqrt(2)         ( 12 points)
//      CODE=3:   (A,A,A) etc, A=1/sqrt(3)         (  8 points)
//      CODE=4:   (A,A,B) etc, B=sqrt(1-2 A^2)     ( 24 points)
//      CODE=5:   (A,B,0) etc, B=sqrt(1-A^2), A input   ( 24 points)
//      CODE=6:   (A,B,C) etc, C=sqrt(1-A^2-B^2), A, B input ( 48 points)

//
//  Parameters:
//
//    Input, int CODE, selects the symmetry group.
//
//    Input/output, int &NUM, the number of points.  This is incremented
//    upon output by the number of points generated on this call.

//    Input, double A, B, information that may be needed to
//    generate the coordinates of the points (for code = 5 or 6 only).
//
//    Input, double V, the weight to be assigned the points.
//
//    Output, double X[*], Y[*], Z[*], W[*], the coordinates
//    and weights of the symmetric points generated on this call.
//
//    Output, int GEN_OH, the number of points generated on this call.
