WebYou can give Sage a short list of elements of a permutation group and Sage will find the smallest subgroup that contains those elements. We say the list “generates” the … The identity element is the all-zero configuration. This monoid is a group … Group Theory and Sage. Basic properties of the integers; Permutation groups; Group … WebApr 7, 2024 · 1 Answer. Yes, the cycle r = ( 1, 2, 3,..., n) is always a suitable element. To find an element s or order 2 such that s r s = r − 1, you can use this trick: D n is the group of isometries of a regular n -agon: if you draw a n -agon and you label the vertices clockwise with numbers { 1, 2,..., n }, you can think that your permutation r is the ...

Web1.6.3 Dihedral group D n The subgroup of S ngenerated by a= (123 n) and b= (2n)(3(n 1)) (i(n+ 2 i)) is called the dihedral group of degree n, denoted D n. It is isomorphic to the group of all symmetries of a regular n-gon. Thm 1.31.
