Note:
you have to activate this ring with the 'setring' command

Example:
 
LIB "ncalg.lib";
def K = Qso3(3);
setring K;
K;
==> //   characteristic : 0
==> //   1 parameter    : Q 
==> //   minpoly        : (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
