I first encountered this problem solving technique of looking at the problem in higher dimension from lectures by tadashi tokieda(referenced in the video). I highly recommend any video of him.

I dont rememer finding many examples, nor a reference to it from common problem solving techniques lists(terry tao, aosp? etc). I think it deserve it's place with a catchier name perhaps

I suggest thinking outside the plane.

A clever strategy, but a name still eludes me

You're either bantering in a higher dimension or you're talking past each other.

Anyway, perhaps a more down to earth "thinking outside the hypercube"?

My reply indicates that that GP was instructed to think outside the plan rather than naming the thing “thinking outside the plane.” It’s a tongue-in-cheek critique of the lack of quotes around the phrase making ambiguous the intent of the parent to my post.
