Using numerical self-consistent solutions of a sequence of finite replica symmetry breakings (RSB) and Wilson's renormalization group but with the number of RSB steps playing a role of decimation scales, we report evidence for a nontrivial T\ensuremath→0 limit of the Parisi order function q(x) for the Sherrington-Kirkpatrick spin glass. Supported by scaling in RSB space, the fixed point order function is conjectured to be q*(a)=\frac√\ensuremathπ2\fraca\ensuremathξ erf(\frac\ensuremathξa) on 0\ensuremath≤a\ensuremath≤\ensuremath∞, where (x)/(T)\ensuremath→a at T=0 and \ensuremathξ\ensuremath≈1.13\ifmmode±\else\textpm\fi0.01. \ensuremathξ plays the role of a correlation length in a-space. q*(a) may be viewed as the solution of an effective 1D field theory.
