We present a revised and extended construction of the mesonic Lagrangian density in chiral perturbation theory (ChPT) at order p6 in the anomalous (or epsilon) sector, L_6,\ensuremathε. After improving several aspects of the strategy we used originally, i.e., a more efficient application of partial integration, the implementation of so-called Bianchi identities, and additional trace relations, we find the new monomial sets to include 24 SU(Nf), 23 SU(3), and 5 SU(2) elements. Furthermore, we introduce 8 supplementary terms due to the extension of the chiral group to SU(Nf)L\ifmmode×\else\texttimes\fiSU(Nf)R\ifmmode×\else\texttimes\fiU(1)V.
