What is "senedj"

Senedj (also known as Sened and Sethenes) is the name of an early Egyptian king ( pharaoh), who may have ruled during the 2nd dynasty. His historical standing remains uncertain. His name is included in the kinglists of the ramesside era, although it is written in different ways: While the kinglist of Abydos imitates the archaic form, the Royal Canon of Turin and the kinglist of Sakkara form the name with the hieroglyphic sign of a plucked goose.

It is also unknown as how long Senedj ruled over Egypt. The Royal Canon of Turin credits him with 70 years of rulership, the ancient Greek historian Manetho states that Séthenes (as he calls Senedj) ruled for 41 years.
