Abstract
We study the symbol of the twoloop ngluon MHV amplitude for all Mandelstam regions in multiRegge kinematics in mathcalN=4 super YangMills theory While the number of distinct Mandelstam regions grows exponentially with n the increase of independent symbols turns out to be merely quadratic We uncover how to construct the symbols for any number of external gluons from just two building blocks which are naturally associated with the six and sevengluon amplitude respectively The second building block is entirely new and in addition to its symbol we also construct a prototype function that correctly reproduces all terms of maximal functional transcendentalityThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
