How many actors were in a greek theater company?

In a typical Greek theater company, there were three main actors, known as protagonists, deuteragonists, and tritagonists. Each actor would play multiple roles throughout the performance. In addition to the three main actors, there was also a chorus, which consisted of a group of singers and dancers who commented on the action of the play. The size of the chorus varied, but it could range from 12 to 50 members.
