What is it that distinguishes Piaget's transformations N, R, and C from the rest of the 16! transformations of the 16 binary propositional operations? Here Piaget's INRC is considered as a subgroup of the group M 2 of all automorphisms and dual autom

Let p be a real representation of a finite group G as n×n matrices and P(p)G the ring of polynomial invariants associated with p(G) One way to describe P(p)G is as a direct sum . Given that such a good polynomial basis is known for P(p)G . we will s
