If I'm understanding your question correctly. The adult Ensemble in Matilda plays Parents in MIracle, School Children, Loud dancer/Judges and each of them have their own smaller part. For example, the ensemble member who plays the Escape Artist also plays a parent in Miracle, a school child, and judge. The woman who plays the Cook also plays a loud dancer, a schoolgirl, and parent. There are 10 adult ensemble members on stage (not including swings.)
