Thank you so very much.  So, if order makes a difference this is a permutation problem?  I tried to figure it out using nPr to get the answer and came up with the same thing you go.  I am grateful for your assistance.

My professor gave up this problem:
Points A, B, C, D, and E are all coplanar and no three are colinear.  In how many ways can the plane be named using only these points?  Assume that different order means different names. 

The only thing the textbook tells me is that a plane is named by the points on it.  It does not discuss different ways to name a plane and I am confused.
