The restricted circular three-body problem is considered for the following
parameter values C=3.03, μ=0.0009537 - the values for {\em Oterma} comet
in the Sun-Jupiter system.
We present a computer assisted proof of an existence of homo- and
heteroclinic cycle between two Lyapunov orbits and an existence of symbolic
dynamics on four symbols built on this cycle.Comment: 40 pages, 11 figure
