(I'm a computer scientist)
Tree branching is a fractal patterns in nature. I know stems typically branch in two at each level (self-similarity). I guess there are plants or other organisms that branch in 3 at each level (still self-similar).
But are there organisms where the stem first branches in 2, then at the next level branches in 3 or more? And maybe at the next (maybe the last) level branches even more, say in 7? It doesn't need to be the stem of a plant, it could be any part of any organism (fungi,...), e.g. the "flower part" of a plant, or a micro-organism.
I'm looking for places where just the branching factor changes, but otherwise little else. What I'm not looking for "branch by 2, branch by 2, branch by 2, and then the very final step is one level of fascicle where branching is 5". I would be fine it's "branch by 2, branch by 3, then fascicle where branching is >3".
I'm trying to find if there is something in nature (e.g. organism, geological, or physical structure) that follows this pattern found in a computer science algorithm, RecSplit, which I co-authored.
Like the following: it first branches in 3, and then branches in 8. The actual numbers don't matter to me, it might as well be branch in 2, then in 3, then in 5, or so.
