We consider further consequences of the recently (Eur. Phys. J. C 78, 632 (2018)) revealed role of cosmological constant as of a physical constant, along with the gravitational one to define the gravity, i.e. the General Relativity and its low-energy limit. We now show how -constant affects the basic relations involving the Planck units and leads to emergence of a new dimensionless quantity (constant) which can be given cosmological information content. Within Conformal Cyclic Cosmology, this approach implies the possibility of rescaling of physical constants from one aeon to another; the rescaling has to satisfy a condition involving and admitting group symmetry. The emerged dimensionless information constant enables to reduce the dynamics of the universe to an algorithm of discrete steps of information increase.
