WebHowever, a 4 by 4 matrix requires the computation of 4+4! = 28 signed elementary products. A 10 by 10 matrix would require 10 + 10! = 3,628,810 signed elementary products! This trend suggests that soon even the largest and fastest computers would choke on such a computation. 5. WebThen the elementary product associated to σ is a 1σ(1)a 2σ(2)a 3σ(3) = a 13a 22a 31 = ceg and since σ is odd, the signed elementary product associated to σ is −ceg. Deﬁnition 6. …
