A search is presented for pairs of light pseudoscalar bosons, in the massrange from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. Thedecay modes considered are final states that arise when one of thepseudoscalars decays to a pair of tau leptons, and the other one either into apair of tau leptons or muons. The search is based on proton-proton collisionscollected by the CMS experiment in 2016 at a center-of-mass energy of 13 TeVthat correspond to an integrated luminosity of 35.9 fb${-1}$. The 2$\mu$2$\tau$and 4$\tau$ channels are used in combination to constrain the product of theHiggs boson production cross section and the branching fraction into 4$\tau$final state, $\sigma\mathcal{B}$, exploiting the linear dependence of thefermionic coupling strength of pseudoscalar bosons on the fermion mass. Nosignificant excess is observed beyond the expectation from the standard model.The observed and expected upper limits at 95% confidence level on$\sigma\mathcal{B}$, relative to the standard model Higgs boson productioncross section, are set respectively between 0.022 and 0.23 and between 0.027and 0.19 in the mass range probed by the analysis.
