The correlator of two chiral BPS operators from the twisted sector of this quiver CFT exhibits non-trivial dependence on the 't Hooft coupling $\\lambda$ already in the planar limit. This dependence was recently determined using localisation and the expansion at large $\\lambda$ contains a subleading contribution proportional to $\\zeta(3) \\lambda^{-3/2}$.
