How many ways are there for everyone to do this so that at the end of the move, each seat is taken by exactly one person?</h3>
There is a 2 by 10 rectangular greed of seats with people. so there are 2 rows of 10 seats.
When the whistle blows, each person needs to change to an orthogonally adjacent seat.
(This means that the person can go to the seat in front, or the seats in the sides).
This means that, unless for the 4 ends that will have only two options, all the other people (the remaining 16) have 3 options to choose where to sit.
Now, if we take the options that each seat has, and we take the product, we will get:
P = (2)^4*(3)^16 = 688,747,536 ways in which the people can take the seats.

X-Axis
When a figure flips over the X-axis, the X coordinate stays the same while the Y-coordinate’s sign is flipped.
Y- axis
When a figure is flipped over the Y- axis the Y coordinate stays the same while the X axis coordinate’s sign is flipped
Example- (x,y)
X axis flipped
(2,5) —> (2,-5)
Y axis flipped
(3,5) —-> (-3,5)
