I noticed that icon repositories like Fontawesome have a lot of different icons for showing sort orders. The more variations I came across, the more confused I got.

I wanted to know what these icons represent.
I know what the arrows mean. Without the alphabet next to the arrow, a down arrow represents descending order while the up arrow represents ascending order. But the numbers and alphabets next to them made things confusing.
