Abstract
We study irreducible representations and characters of Salingaros' vee groups of orders 4, 8, and 16 as 2-groups of exponent 4. In particular, we construct complex irreducible group modules and explicit representations of these groups. We prove a theorem regarding the number of conjugacy classes and the number of inequivalent irreducible representations of degree one and two. We show how to decompose a complex group algebra into irreducible submodules in accordance with Maschke's Theorem. We formulate two algorithms for nd- ing bases for these submodules which rely on the Groebner basis methods. In the end, we provide the character tables of these groups.

An algebra governing reduction of quaternary structures to ternary structures III. A study of generators of the resulting algebra
By applying the reduction matrices of Part I we analyzed in Part II the multiplication tables of generators of the cubic and nonion algebras, deduced the remaining 3 x 3 sub- tables for the resulting algebra, determined...
