Assuming that the question is about
there are 2,627,625 combinations.
The number is only 24 times as large is the order of the groups does, in fact matter. However, if the 4 groups can be of any size (provided their total is 16), the question goes beyond my ability - particularly at this time of the day!

There are many combinations of two numbers that add up to 36. One combination is 20 + 16
There are 18C4 = 18!/[18-4)!4!] = 18*17*16*15/(4*3*2*1) = 3060 combinations.
If they can repeat, then: 17^6=24,137,569 If they can't repeat, then: 17*16*15*14*13*12=8,910,720
2 to the power 16.
The number of possible combinations is 2^4=16. Depending on what you're representing, this could be positive integers (0 to 16), positive and negative (-8 to 7), or some kind of floating point... Depends on what you mean (But whatever kind of numbers you mean, there are still 16 of them.)
