Meridians: Central meridian is straight. The 180th meridians are straight lines bent at the equator. Other meridians are complex curves.
Parallels: Equator is straight. Other parallels are complex curves.
Poles: Points in opposite vertices.
Symmetry: About the central meridian or the equator.
Distortion
Great area distortion near the 180th meridians or at higher latitudes. Conformality fails at the poles and at the intersections of the 180th meridians with the equator.
Usage
Novel whole-world maps.
