Abstract
LetC k denote the graph with vertices (ɛ 1, ...,ɛ k ),ɛ i =0,1 and vertices adjacent if they differ in exactly one coordinate. We callC k thek-cube.
LetG=G k, p denote the random subgraph ofC k defined by letting
for alli, j ∈ C k and letting these probabilities be mutually independent.
We show that forp=λ/k, λ>1,G k, p almost surely contains a connected component of sizec2k,c=c(λ). It is also true that the second largest component is of sizeo(2k).
