  | ### 5.1.67 janet `Syntax:` `janet (` ideal_expression `)` `janet (` ideal_expression `,` int_expression `)` `Type:` ideal `Purpose:` computes the Janet basis of the given ideal, resp. the standard basis if 1 is given as the second argument. `Remark:` It works only with global orderings. `Example:`
        ring r=0,(x,y,z),dp;
        ideal i=x*y*z-1,x+y+z,x*y+x*z+y*z; // cyclic 3
        janet(i);
      ==> Length of Janet basis: 4
      ==> _[1]=x+y+z
      ==> _[2]=y2+yz+z2
      ==> _[3]=z3-1
      ==> _[4]=yz3-y
