Another "coincidence" appears in those upon which Dirac based his large numbers hypothesis if one looks at the fourth entry in the combinatorial hierarchy, and uses Planck's constant to calculate the dimensionless gravitational coupling constant. Since the Combinatorial Hierarchy does not lend itself to a time parameter, this additional coincidence would suggest that Dirac's hypothesis (that these dimensionless coupling parameters are changing) is unlikely to result in large changes in those parameters and that they may in fact be constants.
