parau vrajeS SaH padAnte

परौ व्रजेः षः पदान्ते

Replace pari परि + vraj व्रज् with S ष् when padafinal.

/vArttika to vrazcabhrasjas..., which introduces another exception to coHkuH.

**parivrAj- परिव्राज् + /su → **parivrAT परिव्राट् "mendicant"

**parivrAj- परिव्राज् + /bhis → !**parivrADbhiH परिव्राड्भिः

When not padafinal, the j ज् stays —

**parivrAj- परिव्राज् + /au → !**parivrAjau परिव्राजौ "two mendicants"

Shouldn't parau परौ mean "before /pari"?

The seventh means "before" only sometimes. Here it means "when (there is) /pari (as an /upasarga)".

Why does vraj व्रज् get A आ?

Because some sUtra says so.

Which sUtra?

Finding it's your homework!
