Question

how many transposition s7 has??​

Answer 1

$\huge{\underline{\underline{\underline{\sf{\pink{ﾑɳรᏇɛƦ \: ࿐}}}}}}$

This group is a finite group defined as the symmetric group on a set of size 7. The set is typically taken to be \{ 1,2,3,4,5,6,7 \}.

In particular, it is a symmetric group on finite set as well as a symmetric group of prime degree.
