那庾多（羊主反梵語西國數法名也古云那由他華嚴經阿僧祇品云俱胝俱胝為一阿庾多阿庾多為一那庾多三等數法中此即大數法也）。

那庾多 (*yáng* + *zhǔ* fanqie; Sanskrit [nayuta]; the name of a method of numbering in the Western countries, anciently called 那由他; the 'Chapter on the Incalculable' in the *Avataṃsaka-sūtra* states: 'A koṭi of koṭis is one ayuta; an ayuta of ayutas is one nayuta;' among the three grades of numerical systems, this belongs to the large numbering system).
