Students were challenged to arrange paper cutouts of different fish species on a page while adhering to certain mathematical constraints, such as keeping the total number of fish under a limit. The students with the highest diversity of fish arrangements included Julien Ginter with 32 different fish and a shark, Tessa Verschoor with 61 different fish, Davey Hitzert with 77 different fish, and Anniek van Gemert with 104 different fish.
