초록
An extended directed triple system of orderv/, denoted by EDTS(v), is a pair (V,frak B) where V isa v-set and frak B is a set of transitive triples ofelements of V such that every ordered pair of elements of V iscontained in exactly one member of frak B. We obtain anecessary and sufficient condition for the existence of cyclicEDTS(v)s, and when k=1 or 2, we also obtain a necessary andsufficient condition for the existence of k-rotationalEDTS(v)s.
