Dear Sir I have a question about permutations of 5 points in 3D space . These 5 points are on the surface of a sphere of radius =1. These points are: { {0., 0., 1.}, {0.181636, 0.559017, 0.809017}, {-0.769421, 0.559017, 0.309017}, {-0.769421, -0.559017, -0.309017}, {0.181636, -0.559017, -0.809017} } My question: What are all possible permutations for these 5 points ? What are the permutations after delete similarities? I need your reply Thanks Marwa Ali
