{title2=$n_B=n_F=128$}
The bosons are the metric, two-form, <dilaton>, RR one-form and RR three-form, with physical dimensions $35+28+1+8+56=128$. Two opposite-chirality <gravitinos> and two <dilatinos> supply $2(56+8)=128$ fermionic degrees of freedom. They form the ten-dimensional <type IIA supergravity> multiplet. Counts refer to on-shell polarizations, not raw field components.
