  • Further restrictions on the structure of finite DCI-groups : an addendum
    Dobson, Edward Tauscher, 1965- ; Morris, Joy ; Spiga, Pablo
    A finite group ▫$R$▫ is a DCI-group if, whenever ▫$S$▫ and ▫$T$▫ are subsets of ▫$R$▫ with the Cayley digraphs ▫${\mathrm {Cay}}(R, S)$▫ and▫ ${\mathrm{Cay}}(R, T)$▫ isomorphic, there exists an ... automorphism ▫$\varphi$▫ of ▫$R$▫ with ▫$S^\varphi = T$▫. The classification of DCI-groups is an open problem in the theory of Cayley digraphs and is closely related to the isomorphism problem for digraphs. This paper is a contribution toward this classification, as we show that every dihedral group of order ▫$6p$▫, with ▫$p\geq 5$▫ prime, is a DCI-group. This corrects and completes the proof of C. H. Li et al. [J. Algebr. Comb. 26, No. 2, 161--181 (2007), Theorem 1.1] as observed by the reviewer (Conder in Mathematical Reviews MR2335710).
