What is triple sided paper? My searching isn't giving me anything...

  Probably a mathematical construct, like a 4-dimensional cube.

  He's a mathematician. Musing about how reading a paper would be if paper had three sides. It's not a real thing.

    Thank you! That definitely wasn't clear to me.

  From the previous post: “Can you come up with a good algorithm to read a stack of triple-sided sheets of paper? You may not be familiar with triple-sided sheets of paper, so here’s how they work: they stack nicely, just like regular sheets of paper, but you have to flip one over three times before you get back to the original side. In particular, there are two different operations you can do: call them flip (say, left-right) and anti-flip (right-left). On two-sided paper, flip and anti-flip are the same. On three-sided sheets, two flips are the same as an anti-flip, and two anti-flips are the same as a flip. Of course, three flips, or three anti-flips, are both the same as doing nothing.”

  Imagine a piece of paper with a Y shaped cross section. By smoothing down any two arms of the Y, you can read what's written there. By flipping over an arm, you can read a different side. There are three sides available.

    Why would anyone do this instead of using 4 pages on two sheets of paper ? Wouldn't it be two sheets of paper attached to each other anyway ?

      Isn't the keyword "imagine"? From what I understand, nobody is actually doing this and triple-sided paper doesn't exist in any form. You know, like spherical cows in a vacuum (I assume).

  It could be useful for origami. "You will get a better Gorilla effect if you use as big a piece of paper as possible." -Kunihiko Kasahara, Creative Origami.
