Singular Manual: lpPrint

| ##### 7.7.10.0. lpPrint Procedure from library `freegb.lib` (see freegb_lib). Usage: lpPrint(I, r); I an ideal, r a ring Return: list of strings Purpose: represent Letterplace ideal in the form of words Assume: - basering is a Letterplace ring, r is the commutative ring from which basering has been built Example:
    LIB "freegb.lib";
    ring r = (0,a,b,g),(x,y),Dp;
    def R = makeLetterplaceRing(4); // constructs a Letterplace ring
    setring R; // downup algebra A
    ideal J = x(1)*x(2)*y(3)-a*x(1)*y(2)*x(3) - b*y(1)*x(2)*x(3) - g*x(1),
    x(1)*y(2)*y(3)-a*y(1)*x(2)*y(3) - b*y(1)*y(2)*x(3) - g*y(1);
    list L = lpPrint(J,r);
    L;
    ==> [1]:
    ==>    x*x*y+(-a)*x*y*x+(-b)*y*x*x+(-g)*x
    ==> [2]:
    ==>    x*y*y+(-a)*y*x*y+(-b)*y*y*x+(-g)*y
