Mirabolic subgroup
Imagine you and your friends are all part of a big group, but you each have your own mini-group within it. Your mini-group is called a "subgroup." Now, imagine you have a special power that lets you change shapes and sizes, but you can only do it in certain ways.
A "mirabolic subgroup" is like a mini-group within a bigger group, where all the members have a special power that lets them change shape in a specific way. This way of changing shape is called "mirabolic" because it's like looking at yourself in a mirror - when you change shape, you still look similar to how you did before.
It's like if you could change your height, but only in certain increments - for example, you could only grow or shrink by one inch at a time. This would be your "mirabolic power," and if all your friends had the same power, your mini-group would be a mirabolic subgroup.
