=== Hypernuclei with higher strangeness === Since the Ξ is electrically neutral and its nuclear force interactions are attractive, there are predicted to be arbitrarily large hypernuclei with high strangeness and small net charge, including species with no nucleons. [[nuclear binding energy|Binding energy]] per baryon in multi-strange hypernuclei can reach up to 21 MeV/''A'' under certain conditions,<ref name=jpg08/> compared to 8.80 MeV/''A'' for the ordinary nucleus [[Nickel-62|<sup>62</sup>Ni]].<ref>{{cite web |url=http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/nucbin2.html |website=hyperphysics.phy-astr.gsu.edu |title=The Most Tightly Bound Nuclei |accessdate=October 23, 2019 }}</ref> Additionally, formation of Ξ baryons should quickly become energetically favorable, unlike when there are no Ξ's, because the exchange of strangeness with a nucleon would be impossible due to the Pauli exclusion principle.{{sfn|Gal|Hungerford|Millener|2016|p=43}}
