How many elements are there of order 5 in S7?
No other possibilities exist. Thus there are 360 + 120 + 24 = 504 different elements of order 5 in S7.
How many elements are there in S7?
Solution. 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. Therefore the orders of elements in S7 are 1, 2, 3, 4, 5, 6, 7, 10, 12 and the orders of elements in A7 are 1, 2, 3, 4, 5, 6, 7.

What is the order of S5?
The only possible combinations of disjoint cycles of 5 numbers are 2, 2 and 2, 3 which lead to order 2 and order 6 respectively. So the possible orders of elements of S5 are: 1, 2, 3, 4, 5, and 6.

How many subgroups does Z20 have?
(e) Draw the subgroup lattice of Z20 [Note: 20 = 22 · 5]. We know that there is exactly one subgroup per divisor of 20. These subgroups are arranged ac- cording to divisibility, so to draw a subgroup lat- tice we should first draw a divisibility lattice for the divisors of 20.
What is the maximum order of any element of A10?
Maximum order of an element of A10: By considering all possible partitions of 10, we see that the maximum order is 21 (product of a 7-cycle and a 3-cycle).
Does a group of order 35 contain an element of order 5 of order 7?
It follows from Lagrange’s Thoerem that will be of order 5, 7, or 35. If is of order 35, then is cyclic and thus has elements of order 5 and 7.
Is abelian a S5?
The symmetric group S5 is defined to be the group of all permutations on a set of five elements, ie, the symmetric group of degree five. In particular, it is a symmetric group of prime degree and it is denoted by S5. A group generated by a single element is called cyclic and we know that cyclic groups are abelian.
What is the order of this group?
The Order of a group (G) is the number of elements present in that group, i.e it’s cardinality. It is denoted by |G|. Order of element a ∈ G is the smallest positive integer n, such that an= e, where e denotes the identity element of the group, and an denotes the product of n copies of a.
What is the order of permutation?
We define the order of a permutation written as the product of disjoint cycles to be the least common multiple of the lengths of those cycles. So for , written as the product of disjoint cycles.
Why is A5 easy?
The group A5 is simple. Any normal subgroup N⊲A5 must be a union of these conjugacy classes, including (1). Further, the order of N would divide the order A5. However the only divisors of |A5| = 60 that are possible by adding up 1 and any combination of {12,12,15,20} are 60 and 1.
How many subgroups are there for a group of order 7?
Every element of order 7 generates a cyclic group of order 7 so let us count the number of such subgroups: By the Sylow theorems, the number of subgroups of order 7 is ≡ 1 (mod 7) and divides 168. The only options are 1 and 8.

How many 5 cycles are there?
Since there are 5!/5 = 24 different 5-cycles, we see that there are 2 conjugacy classes of 5-cycles in A5, each with 12 elements.
What are the elements in S5?
(c) The possible cycle types of elements in S5 are: identity, 2-cycle, 3-cycle, 4-cycle, 5-cycle, product of two 2-cycles, a product of a 2-cycle with a 3- cycle.
