So, let’s say you’ve gotten extremely lost, and find yourself in the middle of a flat, infinite field with posts planted into the ground in an infinite grid. There should be a post where you are, but there’s you instead.

Now, from your perspective, some of those posts are going to be visible, and some of those aren’t; if you’re in the middle of the second picture, the ones you’ll see are the ones drawn in black.

Anyways, somebody pointed out that this pattern has a bunch of symmetries (specifically, it’s really really easy to show that this is invariant w/r/t GL(2,ℤ)) so I thought I’d illustrate that. and thats what this is.

great! What kinds of groups can you represent with this method?not sure what you mean…

Well, i think they could be used to represent some kinds of…

I wonder what this sounds like to…

This is the magic hexagon. The numbers add up to 38 along each diagonal/vertical line.

It can be called

themagic hexagon rather thanamagic hexagon because there are no other hexagons numbered 1,2…n with this property, no matter how many layers the arrangement has.(well, except for the one which is just one hexagon with ‘1’ written in it, and that’s hardly magical…)
