I am working on these Klotski puzzles which are really hard to solve, and I got stuck at this one:
It tells me that the puzzle can be solved in 46 moves. I could show my progress, but since most people who help to solve them will use code, I do not think that that will be necessary. Thanks for helping, this might not be the last one I will ask for.
The dark brown block is not moveable and the red one has to be where the red dots are.
