    "abstract": "We continue a series of numerical experiments on many-body systems with\nrandom two-body interactions, by examining correlations in ratios in excitation\nenergies of yrast $J$ = 0, 2, 4, 6, 8 states. Previous studies, limited only to\n$J$ = 0,2,4 states, had shown strong correlations in boson systems but not\nfermion systems. By including $J \\ge 6$ states and considering different\nscatter plots, strong and realistic correlations appear in both boson and\nfermion systems. Such correlations are a challenge to explanations of random\ninteractions.",
