We study the existence of sign-changing solutions with multiple bubbles to the slightly subcritical problem where Ω is a smooth bounded domain in , , and is a small parameter. In particular we prove that if Ω is convex and satisfies a certain symmetry, then a nodal four-bubble solution exists with two positive and two negative bubbles.
