The following tuples could be moved from S to K by knowledge propagation:

ISLIST(z0) → c25(ISNELIST(activate(z0)))
ISNELIST(n____(z0, z1)) → c18(U41'(isList(activate(z0)), activate(z1)), ISLIST(activate(z0)))
ISNELIST(n____(z0, z1)) → c20(U51'(isNeList(activate(z0)), activate(z1)), ISNELIST(activate(z0)))
