| ##### 7.5.10.0. makeQso3 Procedure from library `ncalg.lib` (see ncalg_lib). Usage: 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
