Mar 7 at 20:40 comment added Florian F You also can reverse the numbers, i.e. apply n -> (26-n). That would be less obvious.
Mar 7 at 14:09 comment added Notus_Panda True, both symmetries apply as well as rotations of solutions since the direction of execution would simply be mirrored/rotated as well. I don't mind taking the mirror "solution" away @JaapScherphuis I just figured people could still have those puzzles as "unique" too.
Mar 7 at 13:48 comment added Jaap Scherphuis ... and rotations too. I would not consider those to be different puzzles/solutions.
Mar 7 at 13:40 comment added Matthieu M. I would expect, given the nature of the puzzle, that horizontal and vertical symmetries both always apply, no?
