In particular, they showed that an Order-q-subplanes of PG(2, q³) corresponds to a certain ruled surface in PG(6, q). In this article we show that the converse holds, namely that any ruled surface satisfying the required properties corresponds to a tangent Order-q-subplanes of PG(2, q³).en© Springer Science+Business Media New York 2012Bruck–Bose representation; PG(2, q³); Order q subplanes; 51E20Journal article002013754510.1007/s10623-012-9754-70003341791000102-s2.0-8489907288014779Barwick, S.
