… good codes of coding theory proper, which are instead bound to have “high” codeword
distances. To support this claim we proceed to code optimality and the second inverse problem. …

… theory of the Q p -matrices. Also a new approach to a coding theory, which is based on the Q
p -matrices, … As example we can see in Table 3 the matrix Q 5 and its “inverse” matrix Q −5 , …

… i=0 j=0 A standard result of matrix theory ensures that if A is strictly positive definite, then
the inverse exists and the determinant is not 0 and hence the above pdf is well defined. …
