We prove the existence of 3 4-BPS preons in four-and five-dimensional gauged supergravities by explicitly constructing them as smooth quotients of the AdS4 and AdS5 maximally supersymmetric backgrounds, respectively. This result illustrates how the spacetime topology resurrects a fraction of supersymmetry previously ruled out by the local analysis of the Killing spinor equations.
