  We consider the dimensional reduction to D = 3 of four maximal-rank
supergravities which preserve minimal supersymmetry in D = 11, 7, 5 and 4. Such
"curious" theories were investigated some time ago, and the four-dimensional
one corresponds to an N = 1 supergravity with 7 chiral multiplets spanning the
seven-disk manifold. Recently, this latter theory provided cosmological models
for alpha-attractors, which are based on the disk geometry with possible
restrictions on the parameter alpha. A unified picture emerges in D = 3, where
the Ehlers group of General Relativity merges with the S-, T- and U- dualities
of the D = 4 parent theories.
