No, there are 1000 of them and I have better things to do with my life!
There is only one possible combination as a combination is the same no matter what the order is. There are 120 permutations, which is where the order does matter.
1260.
4! Four factorial. 4 * 3 * 2 = 24 permutations ------------------------
Since there are no duplicate letters in the word RAINBOW, the number of permutations of those letters is simply the number of permutations of 7 things taken 7 at a time, i.e. 7 factorial, which is 5040.
There are 720 possible permutations.

39916800 permutations are possible for the word INFORMATION.
There are 6! = 720 permutations.

Heap's algorithm efficiently generates all possible permutations of a given set by using a systematic approach that minimizes the number of swaps needed to generate each permutation. It achieves this by recursively swapping elements in the set to create new permutations, ensuring that each permutation is unique and all possible permutations are generated.
120?
Normally, there would be 5!=120 different permutations* of five letters. Since two of the letters are the same, we can each of these permutations will be duplicated once (with the matching letters switched). So there are only half as many, or 60 permutations.* (the correct terminology is "permutation". "combination" means something else.)
To efficiently use the np permute function in Python to generate all possible permutations of a given list, you can first import the numpy library and then use the np permute function with the list as an argument. This will return an array of all possible permutations of the elements in the list.
