那庾多（庾音羊主反亦數法名也古云那由他花嚴經云俱𦙁為阿庾多又數中即是上等大數名也皆竆至本方變其名）。

Nayuta (那庾多; yu is pronounced *yang* + *zhu* in fanqie: also the name of a numerical reckoning method, anciently called *nayuta* [那由他]. The *Avataṃsaka-sūtra* states: “A koṭi of koṭis makes an ayuta.” Moreover, within the reckonings, this is the name of a great number of the highest grade. They all alter their names only upon exhausting their base [unit]).
