On Toeplitz codes of index t and isometry codes

Discrete Mathematics, 2023
A square matrix is called Toeplitz, when it is in the following form: \[ A=\begin{pmatrix} a & a_1 & a_2 & \cdots & a_{n-2} & a_{n-1} \\ b_1 & a & a_1 & \ddots & \ddots & a_{n-2} \\ b_2 & b_1 & a & \ddots & \ddots & \vdots \\ \vdots & \ddots & \ddots& \ddots & \ddots & a_2 \\ b_{n-2} & \ddots & \ddots & \ddots & a & a_1 \\ b_{n-1} & b_{n-2} & \cdots ...

Perfect t-codes in Cayley graphs of groups

Discrete Mathematics, Algorithms and Applications, 2021
A perfect [Formula: see text]-code in a graph [Formula: see text] is a subset [Formula: see text] of [Formula: see text] such that every vertex of [Formula: see text] is at a distance not more than [Formula: see text], to exactly one vertex of [Formula: see text].
