No. It is a known result in group theory that the automorphism group of the symmetric group is itself execpt in the exceptional case $S_6$. To see the proof you can read this or you can go here.

i don't know what exactly you are looking for, but all questions you've been asking so far are very well-known results and can be found in almost any decent book in group theory.

for example my favorite is "An Introduction to the Theory of Groups", 4th edition, by Joseph Rotman.

There are not that many authors in algebra who are as brilliant as Joseph Rotman (group and field theory), Louis Rowen (ring theory), Igor Shafarevich (algebraic geometry), ...

Are you sure Rotman has a book on Field Theory?
Maybe you confused it with Roman?
(I made that confusion when I read what you wrote.)

Joseph Rotman's book is called "Galois Theory". Steve Roman's "Field Theory" is great too.

Ah, okay. The book I have is by Morandi. In some ways it is more advanced than Roman - I really like that book.

Do you just not love talking about math book authors as if they are some novels authors that the common people discuss?

Thanx for the info.

If I know the answers I don't put in this thread.

Any way I bought the book, ThePerfectHacker told which is by Morandi. Thanks ThePerfectHacker.

No! That book is not a group theory book, it is not going to have what you want about S_6. Look at my above posts I said field theory not group theory.
