Abstract
Let Fin(v)={(s,t):â a pair of (K4âe)-designs of order v intersecting in s blocks and 2s+t triangles}. Let Adm(v)={(s,t):s+tâ¤bv,sâJ(v),2s+tâJT(v)}â{(bvâ3,1)}, where J(v) (or JT(v)) denotes the set of positive integers s (or t) such that there exists a pair of (K4âe)-designs of order v intersecting in s blocks (or t triangles), and bv=v(vâ1)/10. It is established that Fin(v)=Adm(v) for any integer vâ¡0,1(mod5), vâ¥6 and vâ 10,11.
