WebSep 30, 2024 · To prove the property directly, we can use induction on the size or dimension of the matrix. The basic idea of the proof is that the base case, where A is a one-by-one matrix, is trivial. Assume that the n-1-by-n-1 matrix is diagonalizable, meaning it has n-1 independent eigenvectors). WebLinear codes associated with the Hamming graphs H(n, m) and related graphs were examined, with a view to employing permutation decoding, in . They are good candidates for this decoding method since the combinatorial properties of the graphs and related designs can be used to determine the main parameters of the codes, including automorphism …

WebProof. (Sketch). First we know from the previous proposition that every permutation can be written as a product of transpositions, so the only problem is to prove that it is not possible to find two expressions for a given permutation, one using a product \(s_1 s_2 \cdots s_{2m+1}\) of an odd number of transpositions and one using a product \(t_1 t_2 \cdots … WebProof. Let σa ∈ orb(x), we have to show that it equals one of x, σ(x), …, σr − 1(x). To do that, write a = qr + b where b is the remainder on dividing a by r, so that 0 ≤ b < r. Then σa(x) = σqr + b(x) = σb(σrq(x)). But σr(x) = x, so σ to the power of any multiple of r sends x to itself too. Thus σa(x) = σb(x) ∈ {x, σ(x), …, σr − 1(x)}.
