isPacked -- determines if a given square-free ideal is packed.



Given a square-free monomial ideal $I$, determines if the ideal is Konig. A square-free monomial ideal $I$ of codimension $c$ is packed if every ideal obtained from it by replacing any number of variables by 1 or 0 is Konig.

i1 : R = QQ[x,y,z];
i2 : I = ideal(x*y,y*z,x*z);

o2 : Ideal of R
i3 : isPacked(I)

o3 = false
