There are 14! ways to arrange the numbers 1-14
This turns out to be about
OK... I am in the procsess of building a spreadsheet to help me with route planning but I think I may have stumbled on a problem that someone might be able to help me with.
To put it simply, I have 14 objects and need to list the different combinations that they can be ordered into.
Am I right in saying that there are over eighty seven billion results / combinations or am I working this out wrong?
Well is there any way to find out the number of results under certain rules?
1 has to be before 2
3 has to be before 4
5 has to be before 6
7 has to be before 8
9 has to be before 10
11 has to be before 12
13 has to be before 14
By before I mean to the left of. so it can't start with 2,1 etc.
Is there anyway I can find out how many that leaves me with?
