I’m not sure what a mathematical approach _without_ structuralism would look like. Like, if you consider the operations created by combining the rotations and flips of a triangle, and the set of permutations of the letters A,B and C, it’s pretty obvious they’re isomorphic and also obvious that they’re different. My question is: is there a mathematically useful way of expressing that difference?
Or to put it a different way, I’m not sure anything interesting is being said here.
