Namely, if p is greater than 2d, then all d-dimensional characteristic p representations for H1 can be factored into commuting products of representations, with each factor arising from a representation of the Lie algebra of H1, and conversely any commuting collection of Lie algebra representations gives rise to a representation of H1 in this fashion. In this sense, for a fixed dimension and large enough p, all representations for H1 look generically like representations for direct powers of it over a field of characteristic zero.
