Trivikrama

Trivikrama, Three Steps, is an Indian name. It is a super-constellation in Ursa Major that consists of three constellations of two stars each, Yugma (युग्म) and Yugmaka (युग्मक) (the "double stars" in the ancient sense of the term, meaning two stars very close together but clearly separate for the naked eye). This Indian constellation equals the Chinese constellation Santai (三台) (three steps), but the direction of transfer is yet unknown.
