We show that the E11​ representation that contains the space-time
translation generators also contains the rank two and five totally
anti-symmetric representations of A10​. By studying the behaviour of these
latter A10​ representations under SL(32), which we argue is contained in
the Cartan involution invariant sub-algebra of E11​, we find that the rank
two and five totally anti-symmetric representations must be identified with the
central charges of the eleven dimensional supersymmetry algebra.Comment: 12 pages, plain tex, Typos corrected, one reference and three
