Who name for the theorem

Oh, I am sorry, I don't name for the theorem is Dao's theorem on six circumcenrs, the theorem name by Nikolaos Dergiades and Telv Cohl, and Paul Yiu(the Editor in Chief of the Journal). The first time, Dao Thanh Oai found and he named the theorem is Another Seven Circle theorem at here Another Seven Circles Theorem,(I mean I publish the first time at there). But Nikolaos Dergiades, and Telv Cohl give the proof and publish, they call theorem is Dao six circumcenter theorem. Why I call theorem is Another seven circle theorem? Because it is like as: Seven circles theorem. Thank to You very much -
