In 1995, Hochberg, McDiarmid, and Saks [4] proved that the vertex-band*
*width
of the triangular grid Tn is precisely n + 1; more recently Balogh, Mubay*
*i, and
Pluh'ar [1] posed the problem of determining the edge-bandwidth of Tn. We
show that the edge-bandwidth of Tn is bounded above by 3n - 1 and below by
