毫𣯛（上胡高反下力馳反九章筭經云凡度之始初於忽十忽為絲十絲為毫十毫為𣯛說文云毫𣯛二字並從毛毫字從豪省𣯛字從𣺶省經文作豪𱤉二字誤也）。

Fine hair and minute fraction (毫𣯛: the upper character has the fanqie 胡高; the lower character has the fanqie 力馳. The Jiuzhang suanshu says: "The beginning of all measures starts with a minute dust (hū); ten hū make a silk thread (sī); ten sī make a fine hair (háo); ten háo make a lí (𣯛)." The Shuowen says: "The two characters háo and lí are both formed with [the semantic element] máo (毛). The character háo is formed with háo (豪) abbreviated; the character lí is formed with lí (𣺶) abbreviated." In the sūtra text they are written as 豪𱤉, both characters being erroneous).
