Hamiltonian paths and cycles | Planar graphs | Regular graphs | Individual graphs
In the mathematical field of graph theory, the Tutte graph is a 3-regular graph with 46 vertices and 69 edges named after W. T. Tutte. It has chromatic number 3, chromatic index 3, girth 4 and diameter 8. The Tutte graph is a cubic polyhedral graph, but is non-hamiltonian. Therefore, it is a counterexample to Tait's conjecture that every 3-regular polyhedron has a Hamiltonian cycle. Published by Tutte in 1946, it is the first counterexample constructed for this conjecture. Other counterexamples were found later, in many cases based on Grinberg's theorem. (Wikipedia).

Tuples in Python - Advanced Python 02 - Programming Tutorial
In this Python Advanced Tutorial, we will be learning about Tuples in Python. A Tuple is a collection data type that is ordered and immutable. It is similar to a List with the main difference that a Tuple cannot be changed after its creation. A Tuple is often used for objects that belong t

Tupes are also collections of elements, similar to arrays. There are some differences, though. For one, they are immutable (the elements cannot be changed once created) and the syntax is different from arrays.

The Tuple data type allows you the store a fixed number of values in one place. Tuples are similar to lists and sets, but they are immutable. Typically, the elements of a tuple are related to each other. In this video, we will use IDLE to define tuples and see how they are used in Pytho

Python 3 Programming Tutorial - Lists and Tuples
In this programming tutorial, we cover Python lists and tuples. Both data structures contain data, but are slightly different. Python lists are mutable, meaning they can be changed and manipulated. Tuples are immutable, meaning they cannot be changed. This is what sets them apart and why
