**Something around 1,600,000,000,000,000.** If we imagine a plane an arbitrarily far but non-infinite distance in front of me, I can point each of my fingers such that the ray extended from it will intersect that plane at a single point. Let any parallel rays be considered - for this purpose - to be hitting the same point. Based on this, I can point my ten fingers to generate a set of dots in an arbitrary order in both the X and Y axes, with points possibly being equivalent along one or both axes. This describes the following set of options: If no points are the same, there are 10! ways of ordering along a single dimension = 3,628,800. If a pair of points are the same, then there are 10 choose 2 = 45*9! orders. If a triplet are the same, there are 10 choose 3 = 120 * 8! orders. We continue this sequence on down for a total of (per wolfram Alpha): sum_2^10binomial(10, X) (11-X)!+10! = 26,065,011 But then we have the cases where one set is already paired off and another set gets paired. This is the same problem, but with (10 choose 2) * 8 choose from 2 up to 8 with a factorial on the end, noting that we need to divide the first case in half to avoid duplication. This gives... binomial(10, 2) sum_2^8binomial(8, X) (9-X)!-binomial(10, 2) binomial(8, 2)×(7!)/2 = 5,436,405 We do this again for 10 choose 3 * 7 choose from 2 up to 7 etc etc: binomial(10, 3) sum_2^7binomial(7, X) (8-X)!-binomial(10, 3) binomial(7, 3)×(5!)/2 = 2,184,120 And so on and so forth, keeping in mind that this gets trickier as we have more than two clusters, since we get phrases like Bi(10,2)Bi(8,2)Bi(6,3). I can't do the math at 4:00 am, so I'll approximate that we are at about 40,000,000 total cases. But this is just one axis - we can do the same on the other axis, for a total of ~ 40,000,000^2 = 1,600,000,000,000,000. --- Old Answer --- **268,435,455** If I have my fingers extended, each could reasonably touch any finger or (with some effort) combination of fingers on the other hand. Thus we have five fingers, each with (1+5+10+10+5+1) possible finger combinations they could be touching for a product of 32^5 values. Further, each hand could be either side up, and above or below the other - that's 8 more per option - 8*(32^5), which is 2^28 = **268,435,456** options. Some of these may be tricky to physically achieve, but they should all be possible. Pick your favorite ordering.
