Abstract Algebra: If G is a nonmpty set that is equipped with a binary relation * that satisfies the following axioms:

1. Closure
2. Associativity
3. There is an element e in G s.t. a*e=a=e*a for all a in G
4. For each a in G, there is an element d in G such that a*d=e and d*a=e

Then G is a group under the operation *
The set of integers is a group under addition.

The set of permutations in S_n is a group under composition.
The subset from the complex numbers {1, -1, i, -1} is a group under multiplication.

A small selection of people. Generally named Alyssa, Haylie, Anika, and Mallorie! That Madie claims glares at them all the time! She also claims that Alyssa hates her without actually asking Alyssa before making the assumption.
The little "group" is glaring at me again.

The uber stealth group run by Stiles. They're responsible for making all non-Alb solo stealth feel completely miserable when they zerg each one 200 times a day, while claiming to kill full groups.

We know the truth, though.
"Damnit, Stiles and that warder zerg are out camping the bridge again!"

"Yeah, fuck it, I'm logging"

A group of teens from Winnebago, or the surrounding area. The group consists of Yaya, Nick S., Nick V., John, Matt, Ryry, Poochie, Ryan S., Smithers, and many others. There is a large female population as well, though the females of the group usually depend on who a certain male member of the group is going out with at that time.
At school the group can be found standing at the wall near the pop machines, or by Yaya's locker. Outside of school the group can be found at the park, or the mall, because they are mall rats.
There are many clicks within the larger group.
Me- "...The group."
Ryry- "Who is this group you always talk about?"
