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
Matroid girth the use of girth in graph theory, meaning the length of the shortest cycle in a graph: the girth of a graphic matroid is the same as the girth of its underlying graph. The girth of other classes of matroids also corresponds to important combinatorial problems. For instance, the girth of a co-graphic matroid (or the cogirth of a graphic matroid) equals the edge connectivity of the underlying graph, the number of edges in a minimum cut of the graph. The girth of a transversal matroid gives the cardinality of a minimum Hall set in a bipartite graph: this is
