  We analyze the possibilities of triplet pairing in Sr2RuO4 based upon an idea
of interlayer coupling. We have considered two models differing by the
effective interactions. In one model the quasi-particle spectra have horizontal
line nodes on all three Fermi surface sheets, while in the other the spectra
have line or point nodes on the alpha and beta sheets and no nodes on the gamma
sheet. Both models reproduce the experimental heat capacity and penetration
depth results, but the calculated specific heat is sightly closer to experiment
in the second solution with nodes only on the alpha and beta sheets.
