✦ Synopsis


A pentagonal packing PP(n; t) is a family of t edge-disjoint pentagons in the complete graph K.. A pentagonal packing is maximal if the complement of the union of its pentagons is pentagon-free.

The spectrum S@'(n) for maximal pentagonal packings is the set of sizes t such that there exists a maximal PP(n; t). We determine the extremes of the spectrum S@'(n) for all n. Our results may be viewed as an extension of similar results for maximal partial Steiner triple systems.
