We construct two infinite series of Moufang loops of exponent 3 whose commutative centre (i. e. the set of elements that commute with all elements of the loop) is not a normal subloop. In particular, we obtain examples of such loops of orders 38 and 311 one of which can be defined as the Moufang triplication of the free Burnside group B(3, 3).

具有非正规交换中心的牟芳环

我们构造了两个指数为 3 的无限级数的牟方环,其交换中心(即与环的所有元素可交换的元素集合)不是正常的子环。特别是,我们获得了这种 3 阶循环的示例8和 311其中之一可以定义为自由 Burnside 群的 Moufang 三元组(3, 3)。
