An infinite plane is divided into maximum number of compartments by three non-parallel sticks of infinite length. Then some balls are placed on the plane at t=0. At t =1, they start moving and collision occurs between them. Find the maximum no of collision that can happen at t=infinite. Note that two balls a,b can collide multiple times but it would be counted as a single collision. When a ba
