Helrossi-principal Octratics was a form of mathematics developed by the Givin to calculate hyperspace jumps and travel routes.
History
The equations found by using this form were instrumental during the Clone Wars. In 20 BBY, they enabled Givin warships and other Confederate starships to navigate their own artificial maze created throughout the Corellian Trade Spine, following the Battle of Duro.
