A bstract We analyze the line defect correlation functions decorating the supersymmetric indices of $$ \mathcal{N} $$ N = 4 super Yang-Mills theories with orthogonal and symplectic gauge groups. We obtain exact closed-form expressions for the correlators by means of combinatorial methods associated with the group characters, including the generalized Murnaghan-Nakayama rules. The exact results for the large N correlators lead to the gravity indices for the gravity dual spectrum of the fluctuations of the fundamental string wrapping AdS 2 and those of the fat string, the D5-brane wrapping AdS 2 × ℝℙ 4 .
