Meridians: Complex curves. The axial meridians are straight.
Parallels: Complex curves.
Symmetry: Triaxially about the centroid.
Distortion
Undistorted nowhere. Distortion is particularly acute along angle bisectors.
Origin
The methodology was presented by John P. Snyder in 1992. The methodology applies to any Platonic solid. This is the tetrahedral development. The icosohedral development is commonly referred to now as the ISEA, for icosahedral Snyder equal-area.
