Re: [math-fun] name for 1/8 of sphere

Completely unambiguously, in standard terminology, it's a "right spherical equilateral triangle". I like hemidemisemisphere (in that order), by analogy with hemidemisemiquaver. Spherical octant ought to work, too. --Dan On 2012-07-31, at 12:09 PM, James Buddenhagen wrote:

A friend who is a sculptor asked me if there is a name for the shape of the 8 pieces a solid sphere would fall into if you cut it with 3 mutually perpendicular planes through the center. I couldn't think of any but thought I would ask here. And more generally, is there a name for a 'spherical wedge' bounded by a spherical triangle and the planar faces from the center containing the triangle's edges?
