display N images in all the possible combinations in 3 x 3 matrices

Hi all,

Hope someone can help me.

I have a folder with a set of images. All the images have the same size. What I would like to do is to present all the possible combinations of these images in 3 x 3 grids and save each of them as a JPG. I could do this manually, but I have too many images.

Any help would be very appreciated!

Could you confirm that you want combinations, not permutations? So, for example, it would be okay if the order used was always

first alphabetically, second alphabetically, third alphabetically
fourth alphabetically, fifth alphabetically, sixth alphabetically
seventh alphabetically, eighth alphabetically, ninth alphabetically

relative to each unique subset?

And if you had (say) 15 input images, that you would want 5005 output images ?

Thanks for your reply!

Sorry that I was not clear enough. I think that what I want is a permutation. I have a total of nine images, but to make it simpler, let's say that I have three images (a, b, c) and that I want to display them a 1 x 3 grid with all the possible combinations. This would be something like this: grid 1, a b c; grid 2, b a c; grid 3, b c a; grid 4, a c b; grid 5, b a c; etc.

Please let me know if this does not make sense.

Thanks!

9 images arranged on a 3 x 3 grid in all possible permutations would have 362880 results. Are you sure you want to do that?

9 choices for the first position, 8 choices for the second position, 7 choices for the third position, ... 9! = 362880 total possibilities.

Hi Walter,

Thanks for your reply. I have been doing some simulations wit the function permn and I think that what I want to do is not too convenient. Ideally, I would like to have all the possible combinations, but I think I am going to use a different approach. Thanks again for your reply!
