A geodesic solid. Click the classical operations in order and watch an illustration of the composition: invert, decompose, differentiate, difference, and telescope. Drag to orbit. The canonical order reveals the authored annotation d = 3.000 → α = 1.920; the operations do not measure it from the solid.
Five classical operations. In this order, they take a solid apart and put back only what it says.
