In particular, around 200 metres (660 ft) north of the layer pyramid is a huge mastaba, today known as Mastaba Z500, which yielded eight marble bowls inscribed with the serekh of king Khaba. Reisner and Fisher therefore conclude that "if the mastabas belong to people connected with the king who built the pyramid, it is probable that the king’s name was Khaba". This opinion is shared by most egyptologists who attribute the layer pyramid to Khaba.[3][4]
