We have only one formula for finding min no.of teeth on the pinion to avoid interference as
T(min)=(2*addendum of pinion)/[sin(pressure angle)*sin(pressure angle)].
T(min)=(2*addendum of pinion)/[sin(pressure angle)*sin(pressure angle)].

14° full depth -involute -32 teeth.
Stud with 20° -14 teeth.
14° half depth- 12 teeth.
Stud with 20° -14 teeth.
14° half depth- 12 teeth.
