Math Problem Statement
The unique finite simple group of order 60 is A5
Solution
Yes, you are absolutely correct! The alternating group of order 60 is indeed the unique finite simple group of that order.
Here’s a bit of context:
- is the group of even permutations of five elements, which is a subgroup of the symmetric group .
- The order of is given by , because the symmetric group has order , and is half of that, consisting of the even permutations.
Why is simple?
A finite simple group is one that does not have any non-trivial normal subgroups (subgroups that are invariant under conjugation). is simple because:
- It has no non-trivial normal subgroups.
- It is also the smallest non-abelian simple group.
This makes it a fundamental object in group theory, and it's often studied in the context of both abstract algebra and the classification of finite simple groups.
