I'm not a floorball player, I'm a mathematician. I got recently curious about the floorball ball: it's got 26 holes, which is an unusual number, and I wondered how they are placed on the ball.
It seems there is no regulation for this, certainly it's not in IFF Material Regulations (2016) document. There is some drawing in the appendix, but still, the placement seems to only have some general rules (like minimal distance between holes).
Is it really true that the balls do not have a predefined shape? And if so, what is the most common placement of the holes?
