| Sep 7, 2015 at 14:31 | comment | added | Justin | As a postdoc in a math department using this information for my research, I am puzzled and the tiniest bit offended that this topic is closed because it is not "research level math." But, many thanks to the folks who responded before this happened. | |

| Aug 23, 2015 at 0:28 | comment | added | Justin | Got it! I understand these ideas abstractly but am hoping for a fairly concrete characterization (parameterization, embedding, metric, or something similar) to help use this space in a computational system. The elements of $\mathrm{SO}(3)$ that stabilize the cube are the octahedral group, but as this is not a normal subgroup of $\mathrm{SO}(3)$ I'm not sure how to deal with the resulting quotient in a concrete way. | |
| Aug 23, 2015 at 0:25 | comment | added | Ehud Meir | This equivalence relation just says that two elements are in the same coset of $H$, where $H$ is the stabilizer of the cube inside $SO(3)$. An element which stabilizes the cube will also stabilize the points $\{0,1\}^3$. This set is finite, and it is possible to show that $H$ is also finiet, and to calculate it explicitly. | |
