3 students can be chosen from a class of 30 in (30 x 29 x 28) = 24,360 ways.But each group of the same 3 students will be chosen in six different ways.The number of different groups of 3 is 24,360/6 = 4,060 .

they can be 2 groups of 16, 4 groups of 8, 8 groups of 4, or 16 groups of 2
To divide a class of 32 students into groups with equal numbers of students, you would need to find the factors of 32. The factors of 32 are 1, 2, 4, 8, 16, and 32. Therefore, you can divide the class into 1 group of 32 students, 2 groups of 16 students, 4 groups of 8 students, 8 groups of 4 students, 16 groups of 2 students, or 32 groups of 1 student. So, there are 6 ways to divide the class into groups with equal numbers of students.
Oh, absolutely! Let's take a moment to appreciate the number 23. You can split it into equal groups, like 2 groups of 11 and 1 group of 1. Remember, there are many ways to divide numbers, so feel free to explore and find the one that brings you joy.
2 groups of 16, 4 groups of 8, 8 groups of 4, 16 groups of 2. Not really divided or in groups, but there could be 1 group of 32 or everyone by themselves.

The formula would be: (40!/36!)/4! This gives 2193360/24, or 91,390 unique groups.
There are only two possibilities... 10 groups of 2 or 5 groups of 4. Unless - you can have varying sized groups - which you didn't specify.
