A teacher provides four special lessons, one each in Maths, Music,
English and Science, for some of the children in her class. For the
students in these special lessons:
• there are exactly 3 children in each lesson.
• each pair of students attends at least one special lesson together.
What is the largest number of students who can attend these special
lessons?
