= Maximal nine-dimensional supergravity
{title2=$\mathcal N=2,\quad32\text{ real supercharges}$}
The ungauged maximal nine-dimensional <supergravity> zero-mode multiplet has one metric, three vectors, two two-forms, one three-form and three scalars, giving $128$ bosonic states. Two Majorana <gravitini> and four Majorana spin-one-half fields give $128$ fermionic states. Flat-circle reductions of massless type IIA and type IIB theories, and a flat-two-torus reduction of eleven-dimensional <supergravity>, give this same nonchiral spectrum.
