（广义）四元数群的自同构群及其全形

该文讨论了一类2^n阶非交换群——（广义）四元数群Q_{2^n}=〈a,b|a^{2^n-1}=1,b^2=a^{2^{n-2}},{b^{-1}ab=a^{-1}〉(n≥3)的自同构群A（Q_{2^n}）与全形H（Q_{2^n}））的置换表示，给出了A（Q_{2^n}））与H（Q_{2^n}））的构造.     

Diassociativity in Conjugacy Closed Loops

Abstract

Let Q be a conjugacy closed loop, and N(Q) its nucleus. Then Z(N(Q)) contains all associators of elements of Q. If in addition Q is diassociative (i.e., an extra loop), then all these associators have order 2. If Q is power-associative and |Q| is finite and relatively prime to 6, then Q is a group. If Q is a finite non-associative extra loop, then 16 ∣ |Q|.     

Multiple Holomorphs of Dihedral and Quaternionic Groups

The holomorph of a group G is Norm _B (λ(G)), the normalizer of the left regular representation λ(G) in its group of permutations B = Perm(G). The multiple holomorph of G is the normalizer of the holomorph in B. The multiple holomorph and its quotient by the holomorph encodes a great deal of information about the holomorph itself and about the group λ(G) and its conjugates within the holomorph. We explore the multiple holomorphs of the dihedral groups D _n and quaternionic (dicyclic) groups Q _n for n ≥ 3.
