i dont know much about this subject, so i looked it up and tbh i didnt understand much , i have lots of qs regarding the definition and the caracteristics of fractals.
Anyway i dont think " any combination of an infinite number of connected shapes a fractal"
U can take for example an array that has infinit number of cases (squares conntected to each other), thats not a fractal is it!
But if u add more prepositions to it, maybe it can be a fractal. Maybe. i suggest u do it, i am doing it. u can start by trying to figure out why that example isnt fractal and what its missing and what it needs or what u should adjust or add to ur claim/qs to make it a fractal. construct some other shapes and study them
