Jesse Sakari Hyttinen is a mathematician, programmer and author, and is also a passionate user of partition form and symbolic treespeak. He makes projects in mathematics and programming, and usually combines both aspects of these, and also makes Instagram posts about tree generation and enumeration. Having conducted independent research in the realm of tree generation and enumeration for many years, he has developed a strong intuition especially in rooted tree generation. With the goal of sharing knowledge and building a community for graph theory and treespeak enthusiasts, he wants to show that mathematics can be a form of art, a pinnacle of creativity and also a fun, competitive game as well.
