Dodgson condensation expressions we obtained for formula_48 and dividing out by formula_58 (this is allowed if one thinks of the identities as polynomial identities over the ring of polynomials in the formula_59 indeterminate variables formula_60). Dodgson condensation In mathematics, Dodgson condensation is a method of computing the determinants of square matrices. It is named for its inventor, Charles Lutwidge Dodgson (better known as Lewis Carroll). The method in the case of an "n" × "n" matrix is to construct an ("n" − 1) × ("n" − 1) matrix, an ("n" − 2) × ("n" − 2), and so on, finishing with a
Skeffington Lutwidge of the "Carcass"s cutter as the expedition progressed. By 1800 Lutwidge began to circulate a story that while the ship had been trapped in the ice, Nelson had seen and pursued a polar bear, before being ordered to return to the ship. Lutwidge's later version, in 1809, reported that Nelson and a companion had given chase to the bear, but on being questioned why, replied that "I wished, Sir, to get the skin for my father." Nelson referred to Lutwidge as 'that good old man'. Lutwidge was appointed to command the 28-gun sixth rate in August 1775, and sailed to
