Hi
Four way flashers ( Hazard Flashers ) are so called purely because they flash both front and rear of the vehicle. They operate on all four corners of the vehicle. that's my understanding of 4 Way Flashers.
4*3*2*1 = 24 ways.4*3*2*1 = 24 ways.4*3*2*1 = 24 ways.4*3*2*1 = 24 ways.
4 Possible ways
There are 4! or factorial(4) = 24 ways.
Since there are 4 letters, they can be arranged 4! ways (4*3*2*1) or 24 ways.
4! = 4*3*2*1 = 24 ways
4! 4 * 3 * 2 = 24 ways ==========
There are 8!/(4!*4!) = 70 ways.
4! = 24, they can be arranged in 24 different ways
4*3*2*1 = 24 ways.
You can arrange 4 in 2 ways 1x4 and 2x2.
* * * *
4*4*4 = 64 ways.
