In a chess tournament, a team of schoolchildren and a team of students, each consisting of 15 participants, compete against each other. During the tournament, each schoolchild must play with each student exactly once, with the condition that everyone can play at most once per day. Different numbers of games could be played on different days.

At some point in the tournament, the organizer noticed that there is exactly one way to schedule the next day with 15 games and $N$ ways to schedule the next day with just 1 game (the order of games in the schedule does not matter, only who plays with whom matters). Find the maximum possible value of $N$.
