Please show step by step and explain

What we have shown in the previous exercise is that the two permuta-
tions r and t generate the group Sn. In other words, all of the information
contained in the huge and complicated group S, is characterized in just two
permutations! The study of group generators is an important part of group
theory, but unfortunately it is beyond the level of this course.
