Consider an r-layer hexagon consisting of 3r2 + 3r + 1 hexagonal cells. Can one label the cells by the set N, = {0,1,. . . , 3r2+ 3r) such that each line of adjacent cells are labeled by numbers forming an arithmetic progression modulo (3r2+ 3r + 1) (in proper ordering)? We show that for each r ther
