How many sides must a team number be visible on a robot?

A team's number must be visible on two sides of the robot to ensure proper identification during matches. This requirement helps officials, spectators, and other teams recognize and differentiate robots easily from multiple angles, contributing to better organization and communication during competitions. Making the team number visible on two sides allows flexibility for different orientations and positions that the robot might occupy on the field. This enhances the clarity of the competition logistics without imposing an excessive burden on teams to mark their numbers more than necessary.
