|  |  7.5.10.0. makeUsp1 Procedure from libraryncalg.lib(see  ncalg_lib).
 
Example:Usage:
makeUsp1([p]); p an optional integer (field characteristic)
Return:
a ring, describing U(sp_1)
Note:
You have to activate this ring with the 'setring' command. The presentation of U(sp_1) is derived from the Chevalley representation of sp_1, positive resp. negative roots are denoted by x(i) resp. y(i); Cartan elements are denoted by h(i).
