Horse blanket rear, but usually it has no other straps or attachments. It is intended to be used on a horse while the animal is being led or held by a person, and not left on an unattended horse. In windy weather, a loose surcingle may be added to prevent the cooler from blowing completely off. A traditionally-shaped blanket of loosely crocheted cotton, called an "anti-sweat sheet", is used to absorb moisture. Often used alone to wick moisture from the surface of the horse, if placed under a cooler, it is removed when it becomes wet. A "barrier blanket" is sometimes used
Girth (graph theory) graph is the unique 5-cage (it is the smallest cubic graph of girth 5), the Heawood graph is the unique 6-cage, the McGee graph is the unique 7-cage and the Tutte eight cage is the unique 8-cage. There may exist multiple cages for a given girth. For instance there are three nonisomorphic 10-cages, each with 70 vertices: the Balaban 10-cage, the Harries graph and the Harries–Wong graph. For any positive integers and , there exists a graph with girth at least and chromatic number at least ; for instance, the Grötzsch graph is triangle-free and has chromatic number 4, and
