| ##### 7.5.10.0. makeUso5 Procedure from library `ncalg.lib` (see ncalg_lib). Usage: makeUso5([p]); p an optional integer (field characteristic) Return: a ring, describing U(so_5) Note: You have to activate this ring with the 'setring' command. The presentation of U(so_5) is derived from the Chevalley representation of so_5, positive resp. negative roots are denoted by x(i) resp. y(i); Cartan elements are denoted by h(i). Example:
    LIB "ncalg.lib";
    def ncAlgebra = makeUso5();
    ncAlgebra;
    ==> // coefficients: QQ
    ==> // number of vars : 10
    ==> //        block   1 : ordering dp
    ==> //                  : names    X(1) X(2) X(3) X(4) Y(1) Y(2) Y(3) Y(4) H(\
       1) H(2)
    ==> //        block   2 : ordering C
    ==> // noncommutative relations: ...
    setring ncAlgebra;
    // ...  28  noncommutative relations
