One Reply to “Tiger 4D Toroid fly-through cross section”

  1. Of note, i am supposed to be the co-discover of the tiger.  I was certainly making the right noises when i figured out exactly what Marek Ctrnáct wrote.  The name tiger is a pun, based on japanese toru = tiger.  That was not my doing.

    The tiger is variously ((ii)(ii)) or (ii)(ii)(oo), depending on whether you want to use the older notation or mine.  It’s the comb product of three circles, and because of this, its surface is topologically equal to a box x*y*z. 

    A tiger is what a lattitude of climata looks like on the 4D earth, but you knew that.
