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
Matroid girth oracle, it is impossible to find the girth using a subexponential number of matroid queries. Similarly, for a real linear matroid of rank , with elements, described by an oracle that gives the orientation of any -tuple of elements, it requires formula_1 oracle queries to determine the girth. Computations using a girth oracle (an oracle that reports the smallest dependent subset of a given set of elements) have also been considered. Matroid girth In matroid theory, a mathematical discipline, the girth of a matroid is the size of its smallest circuit or dependent set. The cogirth of a matroid is
