Admin, please delete if too much given. We’ve been looking at an appropriate shape, unsuccessfully, since yesterday. This shape can be partitioned into n identical smaller shapes in a multitude of ways. Question - does each smaller shape contain an empty cell? If so, that would narrow the possibilities. We just can’t get the recycling symbol out of our heads! Nudge gratefully accepted. Please also advise if famous snooker players are a red herring. Thank you.
