Australian Stock Saddle much deeper seat, higher cantle, and knee pads in the front to create a very secure saddle for riders who ride in rough conditions or spend long hours on a horse. The saddle is kept on with a girth attached to billets under the flaps, similar to those on a dressage saddle. A surcingle passing over the seat of the saddle is also used to provide additional safety. The rear of the saddle is sometimes secured by a crupper. A breastcollar is sometimes added. A saddle blanket or numnah is used under the saddle to absorb sweat and to protect
Girth (graph theory) dual graph, and vice versa. These concepts are unified in matroid theory by the girth of a matroid, the size of the smallest dependent set in the matroid. For a graphic matroid, the matroid girth equals the girth of the underlying graph, while for a co-graphic matroid it equals the edge connectivity. Girth (graph theory) In graph theory, the girth of a graph is the length of a shortest cycle contained in the graph. If the graph does not contain any cycles (i.e. it's an acyclic graph), its girth is defined to be infinity. For example, a 4-cycle (square) has
