Abstract
We construct an abelian quotient of the symplectic derivation Lie algebra hg,1 of the free Lie algebra generated by the fundamental representation of Sp(2g,Q). More specifically, we show that the weight 12 part of the abelianization of hg,1 is 1-dimensional for g ⩾ 8. The computation is done with the aid of computers.
