Feet in Orthogonal-Buekenhout-Metz Unitals

Nicolas Abarzua, Rolando Pomareda, Oscar Vega

Given an Orthogonal-Buekenhout-Metz unital $U_{\alpha ,\beta }$, embedded in $PG(2,q^2)$, and a point $P\notin U_{\alpha ,\beta }$, we study the set of feet, ${\tau }_P(U_{\alpha ,\beta })$, of $P$ in $U_{\alpha ,\beta }$. We ch…
