Every Lie supergroup has an associated Lie superalgebra of generators (in general, some of which are bosonic and some fermionic). Which Lie supergroup(s) are generated by the Super-Poincare algebra for $d$ spacetime dimensions and $N$ spinor generators (or, if $d \equiv 2 \text{ mod } 4$, $M$ left-handed and $N$ right-handed spinor generators)?
