What is "nedjeftet"

Nedjeftet is a queen mentioned on reliefs discovered near the pyramid complex of Pepi I (close to the pyramid complex of Queen Inenek-Inti). She was a wife of Pepi. Her name was also that of the 20th nome, later known as the Herakleopolis nome, in Upper Egypt; it is possible her family came from there and the marriage was to strengthen the king's position as opposed to the local lords.
