The smallest non-abelian group has this many elements, and the sum as n goes from one to infinity of one over x squared equals pi squared divided by this integer.
The smallest non-abelian group has this many elements, and the sum as n goes from one to infinity of one over x squared equals pi squared divided by this integer. It is also the greatest number of circles of radius r that can fit around an inner circle of radius r such that all of the outer circles touch the (*) inner one, and the number of vertices on a tetrahedron. It is the coefficient on the x squared term in the expansion of x plus one to the fourth power. For 10 points, name this integer equal to three factorial, the number of faces on a cube.
