makeQso3([n]), n an optional int

Purpose:
set up the U_q(so_3) in the presentation of Klimyk; if n is specified, the quantum parameter Q will be specialized at the (2n)-th root of unity

Return:
ring

Note:
activate this ring with the setring command

Example:
 
LIB "ncalg.lib";
def K = makeQso3(3);
setring K;
K;
==> // coefficients: QQ[Q]/(Q2-Q+1)
==> // number of vars : 3
==> //        block   1 : ordering dp
==> //                  : names    x y z
==> //        block   2 : ordering C
==> // noncommutative relations:
==> //    yx=(Q-1)*xy+(-Q)*z
==> //    zx=(-Q)*xz+(-Q+1)*y
==> //    zy=(Q-1)*yz+(-Q)*x
