Symmetries of the Tetrahedron,s. One, labelled ., passes through a vertex of the tetrahedron and through the centroid of the opposite face; the other, labelled ., is determined by the midpoints of a pair of opposite edges. There are four axes like . and two rotations about each of these, through 2π/3 and 4π/3, which send the tet

Permutations, for example interchanging 1 and 3 while leaving 2 fixed gives a permutation of the first three integers. By a . of an arbitrary set . we shall mean a bijection from . to itself. The collection of . permutations of . forms a group S. under composition of functions. There is very little to check. If
