as according to the first potulate in geomtry and infinite number.
6 = 3*2*1
720
That would be 5x4x3x2x1 or 5! or 120 ways to arrange those objects in a line.
6 different ways
24 different ways.

In a straight line, 21! = 51,090,942,171,709,400,000 or approximately 51 quintillion.
In a straight line, 5! = 5*4*3*2*1 = 120 ways.
24
Not sure what a strait line is! Five people can stand in a straight line, with Jessie third in 24 ways if you ignore left-to-right and right-to-left "reflections".
Mathematically speaking, if you line them up in one straight line, there are 5040 ways. You do 7*6*5*4*3*2*1=5040. The * means multiply.
There are 1680 ways of arranging them is a straight line: fewer if in a circle.
