Spacefiller 2 is a spacefiller that was found by Tim Coe[1] in October 1995 that fills the plane with zebra stripes. In terms of its 187 cells, it was formerly tied with Max as the smallest known spacefiller, but Max has a smaller bounding box: 27×27 versus spacefiller 2's 25×35.[2] Smaller versions of Max have since improved both the bounding box and population further.[3][4]
