दशकुलीं गोपो विंशतिकुलीं चत्वारिंशत्कुलीं वा ॥ कZ_०२.३६.०२ ॥
daśakulīṃ gopo viṃśatikulīṃ catvāriṃśatkulīṃ vā
A gopa (local ward officer) should be assigned over ten families—or twenty families—or forty families.
It fixes a manageable span of control, enabling routine verification of residents and quicker detection of crime, migration, and tax evasion.
