If something is scalable that means that the project is able to operate as it gets bigger.
What's the inverse of this? Suppose I have something that is big, but it can be broken down into subsections and it will still be able to be broken down, etc. — something like a fractal. That is, as it's broken down, it still contains the main components.
For example, I have a list that contains 16 items that can be broken down into 4 main categories, and each category can be broken down further into the same 4 categories. I'm looking for a word to describe this.
