Create a new ticket or edit an existing ticket and navigate to the 'Ticket type' tab. Here, choose 'Group ticket' and then set the group size.

With group tickets, you can sell multiple tickets at once for a fixed price. For example: sell a group ticket for 5 participants for the same price as 4 individual tickets. This encourages people to persuade friends or family to join in at an attractive rate. 

Participants can assign the purchased tickets themselves in the checkout or in the Atleta self-service dashboard.
