Sorry, could you be a little more specific? Are you looking for all suttas that mention bhikkhunis, or just those that mention them in a positive way? (There are a number of suttas that are openly misogynistic).
Do you want to include references to the fourfold assembly, which includes bhikkhunis? Do you want to include passing mentions of “bhikkhus and bhikkhunis”?
I have fairly complete lists of all mentions of bhikkhunis / women in the early texts of the sutta pitaka. Let me know what you need, and I’ll PM it to you.
For starters, you definitely need the Khemasutta, SN 44.1, and the sutta that features the Kajangala bhikkhuni at AN 10.28.
