Triple O'Nan Configurations in Buekenhout-Metz Unitals of Odd Order

An O’Nan configuration in a unital is a set of four lines forming a quadrilateral, where the six intersections of pairs of lines are points of the unital. In 2019 Feng and Li elegantly construct O’Nan configurations in Buekenhout-Metz unitals, in particular, for odd order unitals. We extend their work by showing the existence of Triple O’Nan configurations (a configuration containing three distinct O’Nan configurations) in these odd order Buekenhout-Metz unitals.
