N2 - Energy levels of the double-Λ hypernuclei, ΛΛ7He,ΛΛ 7Li,ΛΛ8Li, ΛΛ9Li,ΛΛ 9Be and ΛΛ10Be are discussed. Interactions between the constituent particles are determined so as to reproduce reasonably the observed low-energy properties of the α + x nuclei, x + Λ, α + x + Λ and α + Λ + Λ systems. With no adjustable parameters for the α + x + Λ + Λ system, BΛΛ of ground and bound excited states of the double-Λ hypernuclei with A = 7-10 are calculated using Gaussian Expansion Method. Furthermore, the four-body caluclation of ΛΛ4H and NNNΞ were peformed. The ΛΛ - ΞN coupling was very important in making ΛΛ4H bound.
