Looks like i probably ended up quitting at the same level Haze01 did. I tried various attempts at first then eventually ended up trying to make each individual glass add up to the same number of corners, but that didn't work. After that I also tried grouping by various criteria simultaneously, like spin direction at bottom left, odd numbered corners on top, and color groups at bottom right, which also didn't work. I don't particularly feel like brute forcing it however, so i'll just leave it be.
