Afghan Checkerboard Patterns with 5 Panels of 5 Colors

Math is everywhere! I finished 5 pink, 5 yellow, 5 blue, 5 white and 5 brown panels for Sarah's Birthday afghan. I was looking online for a program to show me all the combinations (permutations) of the 5 each of 5 colors in a 5x5 grid. But alas, I didn't know how to search so I didn't find it. So I put her to work! Each time she finished a pattern I told her to do another!

After looking at all these photos, she decided she actually wants a different combo...click here for final choice.
