Okay kiddo, do you remember when we talked about groups before? A group is a set of things that we can do operations on, like adding or multiplying. Well, there is a special group called a dicyclic group.
Now, a dicyclic group is just like any other group, but it has some special rules. It has two elements that we’ll call a and b, and we can use them to make other elements in the group. We can do this by using a special formula that goes like this:
a^2 = b^3 = (ab)^2 = (ba)^2 = e
Don't worry kiddo, it might seem confusing, but let me explain each part one by one.
The first part, a^2, means we take the element a and multiply it by itself once. For example, if a was the number 2, a^2 would be 4 because 2 x 2 is 4.
The second part, b^3, means we take the element b and multiply it by itself three times. For example, if b was the number 2, b^3 would be 8 because 2 x 2 x 2 is 8.
The third and fourth parts are a little trickier. They involve multiplying a and b in different orders. (ab) means we first do the operation of a, and then b. So a(b) means we do the operation of b first, and then a.
Finally, the e means the identity element. It's the element that doesn't change anything. So for example, in multiplication, it's the number 1 because any number times 1 is itself.
So with all those rules, we can make a whole set of elements in the dicyclic group. It might sound complicated, but it's a really cool and unique group that mathematicians like to study.
