Re: find all possible answers

What do you mean?

How many sequences can you arrange them into?

If so, then we see that there are 11! ways of arranging them, since no number is repeated.

Or do you mean how each number can be arranged?

23 = 2 arrangements
543 = 6 arrangements
34 = 2 arrangements
135 = 6 arrangements
53 = 2 arrangements
345 = 6 arrangements
24 = 2 arrangements
576 = 6 arrangements
98 = 2 arrangements
69 = 2 arrangements
56 = 2 arrangements

Please explain what you mean.

Re: find all possible answers

Is the order relevant (eg. if it follows an n[sup]th[/sup] term)?
