Visual mus­ings on the math­e­mat­i­cal and exis­ten­tial mat­ter of infin­ity: like love, it’s in the eye of the beholder. Table of dia­grams on right from Don Hatch’s amaz­ing web­site on tes­sel­la­tions and other sundries.

Schlafli and Wythoff sym­bols, enough equa­tions to boon­dog­gle the mind. Wikipedia entry on uni­form tilings on the hyper­bolic plane:

There are an infi­nite num­ber of uni­form tilings on the hyper­bolic plane based on the (p q r) where 1/p + 1/q + 1/r < 1, where p,q,r are each orders of reflec­tion sym­me­try at three points of the fun­da­men­tal domain tri­an­gle – the sym­me­try group is a hyper­bolic tri­an­gle group.

In Hatch’s dia­grams on the right, you can see the var­i­ous tes­sel­la­tions (as depicted on a Poin­caré disk sur­face) trans­form as dif­fer­ent val­ues are inputted — up to infin­ity in the bot­tom right corner.
