A model in which inhomogeneities originated during inflation and transformed eventually into density peaks with maximum wavelength equal to the horizon size at the decoupling epoch (zdec approx. 103) would give at the present for very large scale structure a periodic distribution: 1n (1 + z) approx. 0.04n + 0.04, n = 0, 1, 2, ... . This formula in which the true phase is replaced by its characteristic value fits the data on redshift distribution of distant galaxies fairly well. Some relevant implications are discussed, such as (1) difference between the constants of periodicity C (equivalent to) Delta ln (1 + z): CG for distant galaxies and CQ for quasars, and (2) a recent finding that quasars close on the sky to low redshifted galaxies show a higher concentration toward peaks in the quasar redshift distribution than do quasars in general.
