The seder table also has a stack of three matzas (matzot), representing, among other meanings:

• Cohen-Levi-Yisrael:  The three divisions of Jews
• Abraham-Isaac-Jacob:  The three forefathers

These matzot are used later in the seder for the steps of Motzi and Matza (top and middle matzas); the middle matza becomes the “Afikoman.”
