Commentary

The आर्हीय affix 5.1.63 is optionally elided after a द्विगु occasioning compound, of the word निष्क preceded by द्वि and त्रि।
The word द्विगोः 'a taddhita occasioning a Dvigu compound' of 5.1.28 is to be read into this sutra. Thus द्विनिष्कम् or द्विनैष्किकम्, त्रिनिष्कम् or त्रिनैष्किकम् 7.3.17.

Vart:- So also when nishka is preceded by बहु e.g. बहुनिष्कम् or बहुनैष्किकम् ॥ The irregular Vriddhi of the second term is caused by 7.3.17.
