Abstract

In this paper, we will dive into the deep world of Catalan numbers, exploring interesting examples and why those are Catalan objects. There will be a special focus on Kepler Towers, one specific type of Catalan object that seems to be relatively unstudied and has a nonobvious bijection with Dyck words, another Catalan object.
