Journal of Knot Theory and Its Ramifications, 31(03) 2250022, Mar, 2022 Peer-reviewedWe say that a set of pairs of disjoint cycles [Formula: see text] of a graph [Formula: see text] is linked if for any spatial embedding [Formula: see text] of [Formula: see text] there exists an element [Formula: see text] of [Formula: see text] such that the [Formula: see text]-component link [Formula: see text] is nonsplittable, and also say minimally linked if none of its proper subsets are linked. In this paper, (1) we show that the set of all pairs of disjoint cycles of [Formula: see text] is minimally linked if and only if [Formula: see text] is essentially same as a graph in the Petersen family, and (2) for any two integers [Formula: see text], we exhibit a minimally linked set of Hamiltonian [Formula: see text]-pairs of cycles of the complete graph [Formula: see text] with at most 18 elements.
