In the Secular language this is optional.,
The झलादि case-affixes coming after the above numerals षट्, त्रि and चतुर् may make the words so formed take the acute on the penultimate optionally, in the spoken ordinary language. Thus पंच꣡भिः or पंचभिः꣡ ॥ In the alternative 6.1.179 applies. So also सप्तभिः or सप्तभिः꣡, तिसृ꣡भिः or तिसृभिः꣡ ॥,
