    I’m no mathematician but isn’t the number to the left of big sigma supposed to be 4, to show it’s a series of 4?

      No, it’s a normal multiplication by 3, and it makes sense.

      3 times the sum expands to: 3 * 1/4 + 3 * 1/16 + 3 * 1/64 + 3 * 1/256 + …

      Which is essentially what the picture shows: The main meme is three quarters filled with whole pictures, the fourth quarter being the inset of the sub meme, which is made up of three sixteenths of whole pictures and the fourth sixteenth is made up of the next layer of inset meme etc.

      It’s a sum with n from 1 to infinity. The first value with n=1 is 3/4, with n=2 it’s 3/16. And if you keep adding those terms as n goes to infinity it approaches 1 but never gets there.

      Then if you look back at the meme, you could zoom in for infinity and always find a smaller square.
