Necessary conditions for existence of a resolvable group divisible design (GDD) with block size 3 and type 2 v / 2(a nearly Kirkman triple system, NKTS( v )), are v ≥ 18 and v ≡ 0 (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 .
