Query: System of roots of very special sandwich algebras   This paper continues the study of very special sandwich algebras. We show
that a class of very special sandwich algebras has an analogue of a root system
of a semisimple Lie algebra. This leads to an analogue of a Weyl group, which
we study in another paper.
