The number of different groups of students that can be formed from 16 students depends on the size of the groups being formed. If you are looking for all possible combinations of groups of any size (from 1 to 16), you can use the formula for combinations. The total number of combinations would be (2^{16} - 1) (subtracting 1 to exclude the empty group), which equals 65,535 different groups. If you specify a particular group size, the calculation would be different.
20 x 19 x 18/3 x 2 = 1,140 groups

This depends on whether you do mean sets or if you mean groups as the two are different and often people use the word set when they mean group. 24 groups can be formed and you can calculate this by using the permutation function. 4 possible elements to select from to go into 3 slots, 4P3=24 groups. (Note I said 4 elements not 5, as by definition an element can not be repeated in a set so the set is not {1,2,3,4,4} but {1,2,3,4} unless you mean {1,2,3,44} but this doesn't change anything.)However, while 24 groups can be formed this is not true for sets, groups are structured unlike sets so a group of (1,2,3)≠(2,3,1), but a set{1,2,3}={2,3,1} i.e. the order of the elements matters in a group but not in a set, so only 6 sets of 3 elements can be made compared to 24 groups.
