Eight triangles voting unanimously to become the world's most agreeable solid.
means A three-dimensional geometric solid with eight flat faces, each an equilateral triangle, meeting at six vertices and twelve edges — picture two square-based pyramids glued base to base.
from From Greek 'oktaedron,' built from 'okta-' (eight) and 'hedra' (seat, base, or face). That same '-hedron' sits beneath tetrahedron, dodecahedron, and the whole Platonic family — literally naming each solid by counting its 'seats.' The octahedron is one of the five Platonic solids the ancient Greeks revered; Plato himself associated it with the element air.
