The sylow theorems

WebWe work toward a small generalization of Theorem A in the introduction. (2.1) Lemma. Suppose that G is a group of odd order. Let C be the conjugacy class in G of x ∈ G. If H = Gal(Q(C )/Q) has a cyclic Sylow 2-subgroup, then x is a p-element for some prime p. Proof. Let n be the order of x. WebAug 15, 2024 · Sylow Theorem (Theorem 36.11), the number of Sylow 5-subgroups is either 1 or 6, and the number of Sylow 3-subgroups is either 1 or 10. But is G has 6 distinct Sylow 5-subgroups, then the intersection of any two such subgroups is again a subgroup (Theorem 7.4) and so must have an order that is a divisor of 5 (Theorem of Lagrange, Theorem …
