Abstract: We computationally investigate a weight 3 analogue of the relationship between higher Bloch groups, algebraic K-theory, higher regulators, and special values of Dedekind zeta functions. In particular, for F a number field F, we define the pruned Bloch group B _3(F) and compare the covolume of its regulator lattice with zeta_F(3). We define a quantity kappa_3(F), which is conjecturally an integer, that is expected to be closely related to the order of K_4(O_F).
