1	data(purum)

The Purums are an isolated tribe in the interior of India, divided into five “sibs”: Marrim, Makan, Parpa, Thao, and the Kheyang.

Marriages between persons of the same sib are forbidden, as are persons from certain pairs of sibs; note the lack of symmetry in the structural zeros implying a gender asymmetry (the single Kheyang-Kheyang marriage has special dispensation).
