Sidewalk (or pavement) is a 14-cell still life made up of two islands that are by themselves referred to as sides. An individual side can occasionally be useful as an induction coil.
It is the thirty-sixth most common object on Catagolue in the symmetry the object has (C2_2). In asymmetric soups, it is the 150th most common still life.
Peter Raynham found a 4-glider synthesis for the still life in 1973, which is based on a head-to-head collision between two pi-heptominoes.[1]
