Abstract
The orthogonality relations for the idempotent generators for constacyclic codes are studied. It turns out that these relations give rise to a square table for these idempotents such that the rows are indexed by constacyclonomials and the columns by generating irreducible polynomials (or constacyclotomic cosets), and such that there is orthogonality, by using weight factors, between rows as well as between columns. This phenomenon resembles the properties of the character table of a finite group. This resemblance is strengthened by the existence of conjugated constacyclonomials and conjugated irreducible polynomials (or conjugated constacyclotomic cosets).
