Pointless Topology is a four-and-a-half bedroom apartment in the Mission, home to five people united by a common love of free software and interest in obscure branches of mathematics.

The name derives from a subfield of topology that, unlike most branches of topology which study points and the lattices formed by sets of points, treats the lattices themselves as basic elements.
