We test the spectrum of string theory on AdS_5 x S^5 derived inhep-th/0305052 against that of single-trace gauge invariant operators in freeN=4 super Yang-Mills theory. Masses of string excitations at critical tensionare derived by extrapolating plane-wave frequencies at g_{YM}=0 down to finiteJ. On the SYM side, we present a systematic description of the spectrum ofsingle-trace operators and its reduction to PSU(2,2|4) superconformal primariesvia a refined Eratostenes' supersieve. We perform the comparison of theresulting SYM/string spectra of charges and multiplicities order by order inthe conformal dimension \Delta up to \Delta=10 and find perfect agreement.Interestingly, the SYM/string massive spectrum exhibits a hidden symmetrystructure larger than expected, with bosonic subgroup SO(10,2) and thirty-twosupercharges.Comment: 28 pages, LaTeX2
