Finite Permutation Groups Helmut Wielandt
Publisher:

Group S_n formed by the permutations of elements of a set of n-elements. A finite group is described by giving the complete product table. Quite concretely – and a finite set \Gamma=\{1,\dotsc,n\} be given. We are going to be more explicit and to work out some simple examples/exercises about elementary finite and infinite groups in this post. If the group consists of the elements. In fact, almost all finite groups are non-abelian, so the cyclic groups are just very few in number. The group isomorphism problem is about multiplication tables. By a standard result, this implies that the diameter of every transitive permutation group is small, again with respect to any set of generators. Then the table is {n \times n} in size .. For example, I applied this strategy to reduce the time required to check whether a permutation can be sorted with k or fewer transpositions from O((3k)^{3k}) to O(k logk * (3k)^{1.5k}).
