Unweighted linear congruences with distinct coordinates and the Varshamov--Tenengolts codes

Khodakhast Bibak, Bruce M. Kapron, Venkatesh Srinivasan

In this paper, we first give explicit formulas for the number of solutions of unweighted linear congruences with distinct coordinates. Our main tools are properties of Ramanujan su…
