We prove the conjecture of Abbott and Katchalski that for every m ~> 2 there is a positive constant 2,. such that S(K~n ) >~ 2mnd-lS(Ka~ -1) where S(Ka~) is the length of the longest snake (cycle without chords) in the cartesian product K~ of d copies of the complete graph Kin. As a corollary, we co
