Abstract

Let QpdQ^d_p be the random subgraph of the dd-dimensional binary hypercube obtained after edge-percolation with probability pp. It was shown recently by the authors that, for every ε>0\varepsilon > 0, there is some c=c(ε)>0c = c(\varepsilon)>0 such that, if pdcpd\ge c, then typically QpdQ^d_p contains a cycle of length at least (1ε)2d(1-\varepsilon)2^d. We strengthen this result to show that, under the same assumptions, typically QpdQ^d_p contains cycles of all even lengths between 44 and (1ε)2d(1-\varepsilon)2^d.
