# Is the Landau-Ramanujan constant irrational?

Hi, here, in wikipedia, the Landau-Ramanujan constant appears under a list of suspected transcendentals. I could not find anywhere a statement or a proof of it's irrationality. So, my question is, is the constant irrational( since it's under a list of suspected transcendentals, is it right to assume that it is irrational?) And if it is, is there a proof available? Thanks in advance.

Every number is a suspected transcendental, unless there's some compelling reason to believe it's algebraic. –  Gerry Myerson Sep 13 '10 at 13:07
