We describe three analytic classes of infinitely many AdSd supersymmetric solutions of massive IIA supergravity, for d=7,5,4. The three classes are related by simple universal maps. For example, the AdS7\ifmmode×\else\texttimes\fiM3 solutions (where M3 is topologically S3) are mapped to AdS5\ifmmode×\else\texttimes\fi\mathrm\ensuremathΣ2\ifmmode×\else\texttimes\fiM3^\ensuremath', where \mathrm\ensuremathΣ2 is a Riemann surface of genus g\ensuremath≥2 and the metric on M3^\ensuremath' is obtained by distorting M3 in a certain way. The solutions can have localized D6 or O6 sources, as well as an arbitrary number of D8-branes. The AdS7 case (previously known only numerically) is conjecturally dual to an NS5-D6-D8 system. The field theories in three and four dimensions are not known, but their number of degrees of freedom can be computed in the supergravity approximation. The AdS4 solutions have numerical ``attractor'' generalizations that might be useful for flux compactification purposes.
