There is a single ball at the top; beneath that there is a row with two balls; beneath that there is a row with three balls, then four, then five, then six.
Below all this is a row with seven balls and a particular subset of two of those balls is highlighted. The diagram illustrates a correspondence from that pair to a particular ball in the upper collection.
