The video introduces TREE(3), a number vastly larger than Graham's Number, derived from a game involving trees and seeds. The game has specific rules about tree containment and the nearest common ancestor. TREE(1) and TREE(2) are determined through examples, while TREE(3) is described as unimaginably large, with no known upper bound but a lower bound involving Ackermann numbers. The video concludes with an invitation to explore more about TREE(3) on a secondary channel.
