Query: N=8 Supergravity in Central Charge Superspace   We present a geometrical description of N=8 supergravity, using central
charge superspace. The essential properties of the multiplet, like self-duality
properties of the vectors or the non-linear sigma model structure of the
scalars, are found as consequences of constraints at 0 and 1/2 canonical
dimension. We also present in detail how to derive from this geometrical
formulation the supergravity transformations as well as the whole equations of
motion for the component fields in order to compare them with the results
already known and obtained in formulations on the component level.
