Abstract We develop new techniques to compute five-point correlation functions from IIB supergravity on AdS5 × S 5. Our methods rely entirely on symmetry and general con- sistency conditions, and eschew detailed knowledge of the supergravity effective action. We demonstrate our methods by computing the five-point function of the 20 ′ operator, which is the superconformal primary of the stress tensor multiplet. We also develop systematic methods to compute the five-point conformal blocks in series expansions. Using the ex- plicit expressions of the conformal blocks, we perform a Euclidean OPE analysis of the 20 ′ five-point function. We find expected agreement with non-renormalized quantities and also extract new CFT data at strong coupling.
