Michael Brand proved that the density of Friedman numbers among the naturals is 1, which is to say that the probability of a number chosen randomly and uniformly between 1 and "n" to be a Friedman number tends to 1 as "n" tends to infinity. This result extends to Friedman numbers under any base of representation. He also proved that the same is true also for binary, ternary and quaternary orderly Friedman numbers. The case of base-10 orderly Friedman numbers is still open.
