Cyclic m-DCI-groups and m-CI-groupsKovács, István (Avtor) Šinkovec, Luka (Avtor) Cayley graphcyclic groupm-CI-groupm-DCI-groupBased on the earlier work of Li from 1997 and Dobson from 2008, in this paper we complete the classification of cyclic m-DCI-groups and m-CI-groups. For a positive integer m such that m ≥ 3, we show that the group ℤ_(n) is an m-DCI-group if and only if n is not divisible by 8 nor by p² for any odd prime p < m. Furthermore, if m ≥ 6, then we show that ℤn is an m-CI-group if and only if either n ∈ {8, 9, 18}, or n ∉ {8, 9, 18} and n is not divisible by 8 nor by p² for any odd prime p < (m - 1)/2.20252025-04-01 15:34:57Neznano21153UDK: 519.17ISSN pri članku: 2590-9770DOI: 10.26493/2590-9770.1740.b72COBISS.SI-ID: 230978307sl
