What is "qahedjet"

Qahedjet (also Hor-Qahedjet) could be the horus name of an Ancient Egyptian king ( pharaoh) who may have ruled during the 3rd dynasty or could be a voluntarily archaistic representation of Thutmose III. Since the only artifact attesting the ruler and his name is a small stela made of polished limestone of uncertain origin and authenticity, egyptologists are discussing the chronological position and historical figure of Qahedjet.
