Binary, Hanoi, and Sierpinski - Part 2 of 2

The video explores a constrained variant of the Towers of Hanoi puzzle, where disks can only move to adjacent spindles. The solution involves recursive problem-solving and counting in ternary, mirroring the Sierpinski triangle's structure. The video also discusses the graph representation of configurations and demonstrates a path through the Sierpinski graph using ternary counting.
