Recently, I just watched the group of high school people’s teachings 3-3. I just knew that the group was a kind of symmetrical thing. Some simple operations appeared when they saw the necklace and beads. Over

Two rotation groups can be written as the following forms:
|
a1
a2
…
an 1 r
|
| b1 | B1
b2
…
bn-1
bn
| n |
a2
a3
…
an
a1
|
|
b2
b3
…
bn nb1
| n Left (A1 ,
b1), is to replace the A1 in the following row to B1, B1 to A1, and get
|
a1 r
…
an- 1
an
B1
B2
…
bn-1
|
|
a2 na3
…
an
b1
b2
b3
…
a1
|
The group, because there is a B1 connection in the middle, the last row below is A1, which is the same as the first element above.
Swriting as B1, B2..bm, A1, A2, A3 …..).
