䋞縆（上音冈下古恒反考聲縆大索也經從亘作絙誤略也玉篇音胡官反緩也又是古文亘字非經義也）。

䋞縆 (Nets and thick ropes: the first is pronounced gang 冈. The second [geng has] the fanqie 古恒; the Kaosheng says: 'Geng means a great rope.' In the sūtra text it is written with gen 亘 as 絙, which is an erroneous abbreviation. The Yupian pronounces it with the fanqie 胡官, meaning slack and loose; it is also an ancient form of gen 亘, not the meaning intended in the sūtra).
