Re: Isomorphism Is Where It’s At • “Are there more good cases of isomorphism to study?”

Just off the top of my head, as Data says, a couple of examples come to mind.

Sign Relations. In computational settings, a sign relation L is a triadic relation of the form L \subseteq O \times S \times I, where O is a set of formal objects under consideration and S and I are two formal languages used to denote those objects. It is common practice to cut one’s teeth on the special case S = I before moving on to more solid diets.

Cactus Graphs. In particular, a variant of cactus graphs known (by me, anyway) as painted and rooted cacti (PARCs) affords us with a very efficient graphical syntax for propositional calculus.

I’ll post a few links in the next couple of comments.
