Two A4 modular symmetries for Tri-Maximal 2 mixing

We construct a lepton flavour model based on two A4 modular symmetries. The are broken by bi-triplet field to the diagonal subgroup, resulting in an effective symmetry with moduli. employ these moduli as stabilisers, that preserve distinct residual symmetries, enabling us obtain Tri-Maximal 2 (TM2) mixing minimal content, flavonless at scale, below breaking single A4.
