Popis: Necessary conditions for existence of a resolvable group divisible design (GDD) with block size 3 and type (a nearly Kirkman triple system, NKTS(v)), are and (mod 6). In this paper, we look at doubly resolvable NKTS(v)s; here we find that these necessary conditions are sufficient, except possibly for 64 values of v.
