Meridians: Central meridian is a straight line ⅔ as long as the equator. Other meridians are complex curves concave toward the central meridian.
Parallels: Complex curves convex toward the straight equator. Perpendicular to the central meridian.
Poles: Curves.
Symmetry: About the central meridian and the equator.
Scale
Scale is constant along the equator, being 5/6ths of true scale.
Distortion
Free of distortion nowhere. Distortion is largely in the form of angular deformation below the arctic and antarctic circles, but then transitions into inflation.
Similar projections
