Let V be a complex vector space with a non-degenerate symmetric bilinear form and S an irreducible module over the Clifford algebra C ℓ (V) determined by this form. A supertranslation algebra is a Z-graded Lie superalgebra m= m− 2⊕ m− 1, where m− 2= V and m− 1= S⊕⋯⊕ S is the direct sum of an arbitrary number N≥ 1 of copies of S, whose bracket [⋅,⋅]| m− 1⊗ m− 1: m− 1⊗ m− 1→ m− 2 is symmetric, so (V)-equivariant and non-degenerate (that is the condition “s∈ m− 1,[s, m− 1]= 0” implies s= 0). We consider the maximal transitive prolongations in the sense of Tanaka of supertranslation algebras. We prove that they are finite-dimensional for dim V≥ 3 and classify them in terms of super-Poincaré algebras and appropriate Z-gradings of simple Lie superalgebras.
