Given experimental evidence at the LHC for physics beyond the standard model,how can we determine the nature of the underlying theory? We initiate anapproach to studying the "inverse map" from the space of LHC signatures to theparameter space of theoretical models within the context of low-energysupersymmetry, using 1808 LHC observables including essentially all thosesuggested in the literature and a 15 dimensional parametrization of thesupersymmetric standard model. We show that the inverse map of a point insignature space consists of a number of isolated islands in parameter space,indicating the existence of "degeneracies"--qualitatively different models withthe same LHC signatures. The degeneracies have simple physicalcharacterizations, largely reflecting discrete ambiguities in electroweak-inospectrum, accompanied by small adjustments for the remaining soft parameters.The number of degeneracies falls in the range 1
