Constructed from a beam with a square-root-2 rectangle as cross section. Uses skew miter joints, where the cut faces are squares. The joint angles are 90 and 120 degrees. All 24 segments are identical (trapezoid shaped).
Among all 62688 closed shapes made from 24 such segments, the Right-angle Champion has the most right angles (14, to be precise).
