Saddle in various other Indo-European languages, including the Latin "sella". In addition to the above basic components, some saddles also include: There is evidence, though disputed, that humans first began riding the horse not long after domestication, possibly as early as 4000 BC. The earliest known saddle-like equipment were fringed cloths or pads used by Assyrian cavalry around 700 BC. These were held on with a girth or surcingle that included breast straps and cruppers. From the earliest depictions, saddles became status symbols. To show off an individual's wealth and status, embellishments were added to saddles, including elaborate sewing and leather
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
