A triangle‐free graph  G  is called  k‐existentially complete  if for every induced  k ‐vertex subgraph  H  of  G , every extension of  H  to a    (  k  +  1  )   ‐vertex triangle‐free graph can be realized by adding another vertex of  G  to  H . Cherlin [11][G. L. Cherlin, 1993], [12][G. L. Cherlin, 2011] asked whether  k ‐existentially complete triangle‐free graphs exist for every  k . Here, we present known and new constructions of 3‐existentially complete triangle‐free graphs.
