We have the orthosymplectic $osp(n,m|2k)$. The bosonic part is $so(n,m)\times sp(2k)$. The lie algebra generators are given in eg
where the group is described as a supermatrix acting on super space. For the groups $so(n,m)$ it is easy to go from the lie algebra to the group by exponentiating, these group elements will just be Lorentz transformations in a signature $(n,m)$ space time. Also the same can be done for $sp(2k)$. However, when including the anticommuting generators, is it possible to go from the lie algebra generators to the group by exponentiating? Is there a supermatrix representation of this group?
