Ginn Jump

The Ginn Jump was a part of the Arrowhead region, in the Slice portion of the Core Worlds. At some point between the collapse of the Infinite Empire around 25,200 BBY and the foundation of the Galactic Republic in 25,053 BBY, a Duros hyperspatial physicist romantically—yet relatively inaccurately—proclaimed the Ginn Jump and the star systems of Coruscant, Corellia, and Alderaan—which had long been inhabited by Humans—as the four "vertices" of a region of space that resembled a tetrahedron and was thus accordingly named the Tetrahedron.
