Commentary
The penultimate of चुरादि (10th Conjugation) - छद् is shortened before the affix घ -- पुंसि संज्ञायां घः प्रायेण 3.3.118, when not preceded by two prepositions (or more).
As उरश्छदः, प्रच्छदः, दन्तच्छदः ॥ But समुपच्छादः with two prepositions. The same when preceded by more than two prepositions, as समुपातिच्छादः ॥ The elision of णि of छादि &c., by 6.4.51, should not be considered as asiddha 6.4.22 or sthanivat 1.1.57, otherwise there would be no penultimate to be shortened.
Vart:- The prohibition with regard to द्वि should be extended to numbers more than two.
