  • On the point stabilizers of transitive groups with non-self-paired suborbits of length 2
    Marušič, Dragan ; Nedela, Roman
    In our recent article a characterization of transitive permutation groups having a non-self-paired suborbit of length 2 (with respect to which the corresponding orbital graph is connected) was ... obtained in terms of their point stabilizers. As a consequence, elementary abelian groups were proved to be only possible abelian point stabilizers arising from such actions, and ▫$D_8$▫ was shown to be only nonabelian group of order 8 with the same property. Constructing of such group actions with point stabilizers isomorphic to ▫$D_8$▫ or to ▫$\mathbb Z_2^h$▫, ▫$h\ge 1$▫, were also given there. These results are extended here to include a more in depth analysis of the structure of point stabilizers of such group actions, resulting in a set of necessary conditions allowing us to obtain a restricted list of 19 possible candidates for point stabilizers of such group actions when the point stabilizers have order ▫$2^h$▫, ▫$h\le 8$▫. (For ▫$h\le 5$▫, this list gives a complete classification of such point stabilizers). Furthermore, a construction of a transitive permutation group action with a non-self-paired suborbit of length 2 and point stabilizer isomorphic to ▫$D_8 \times \mathbb Z_2^{h-3}$▫ is given for each ▫$h\ge 3$▫.
