WebSolution. Orders of permutations are determined by least common multiple of the lengths of the cycles in their decomposition into disjoint cycles, which correspond to partitions of 7. Representative Cycle Order Sign 1 Even (12) 2 Odd (123) 3 Even (1234) 4 Odd (12345) 5 Even (123456) 6 Odd (1234567) 7 Even (12)(34) 2 Even (12)(345) 6 Odd (12 ... Web2. For each of the permutations of question 1 say, giving a reason, whether it is even or odd. Solution: (a) This is an 8-cycle. It is odd, since 8 is even. (b) This is even; it is a product of two transpositions. (c) This is a 7-cycle and hence is even. (d) This is even; it is a product of six transpositions. 3.
WebTrue. The definition of even and odd permutations could have been given equally well before theorem 9.15. If a permutation can be expressed in a product of an even number of … Webthe subset of even permutations and the set ˝A n, where ˝is any odd permutation, which is the same as the set of odd permutations and hence equals S n A n.

Web7 which correspond to even permutations. Since a 1 a 2 a r = a 1 a r a 1 a r 1 a 1 a 3 a 1 a 2; an r-cycle is even if and only if ris odd. Thus, in writing a permutation ˙in disjoint cycle form, ˙is even if and only if there are an even number of cycles of even length. Thus, a single rcycle in A 7 must have order 3, 5, or 7. If ˙is a product ... Weba. (F) Every permutation is a cycle. b. (T) Every cycle is a permutation. c.
