      abstract     = {The hexagonalisation technique arose in the context of N=4
                      SYM theory to address the tessellation of the effective
                      world-sheet describing three-point functions of single trace
                      operators. Despite its apparent technical difficulty,
                      exploiting the knowledge of all its ingredients at finite 't
                      Hooft coupling one can perform some non-trivial limits, like
                      the strong-coupling one. In this case, a phenomenon called
                      "clustering" allows the complete resummation of finite-size
                      effects leading to the semi-classical string answer. I will
                      introduce the general background and then discuss the
                      generalization to some particular class of five-point
                      functions, where the clustering phenomenon becomes more
                      involved, involving cross-ratios and some analytic
                      continuation of the ingredients to unusual kinematic
                      regimes. In the end, I will speculate about some tentative
                      directions that one could take.},
