Leptrois

Leptrois, also known as the leptive or leptral gender system, is a gender classification that brings mathematical and linguistic understanding of genders, such as between negative and positive, negatrois and positrois. Leptrois also includes leptarity.

Under leptrois, each gender has an associated spectrum from negatrois (antigender) to positrois (eugender), passing through centrois (nongender). Identities that are both negatrois and positrois for the same gender are known as nulltrois (zerogender). Neutrois is centrois for every gender.
