Possibility #5

When ṃ is followed by y, they can be assimilated into ññ

e.g. saṃ + yojana > saññojana

In Kaccāyana this is called (33) sa ye ca.

ṃ + y > ññ

yaṃ	yaṃ eva	yaññadeva	whatever it is
saṃ	yata	saññata	pp. self-controlled
saṃ	yoga	saññoga	m. bond, tie
visaṃ	yutta	visaññutta	pp. detached, unyoked

Counter-example:

saṃ + yoga > saṃyoga

anu + saṃ + yāyitvā > anusaṃyāyitvā

saṃ + yutta > saṃyutta

imasmiṃ + yeva > imasmiṃyeva
