We present the first direct search for exotic Higgs boson decays H *> *A*A*, A *> *g*g in events with two photonlike objects. The hypothetical particle *A is a low-mass spin-0 particle decaying promptly to a merged diphoton reconstructed as a single photonlike object. We analyze the data collected by the CMS experiment at *%s = 13  TeV corresponding to an integrated luminosity of 136  fb*−*1. No excess above the estimated background is found. We set upper limits on the branching fraction B(H *> *A*A *> 4g) of (0.9–3.3) x 10*−*3 at 95% confidence level for masses of *A in the range 0.1–1.2 GeV.
