Paris Pamfilos, A gallery of conics by five elements,
Forum Geometricorum, 14 (2014) 295--348.
Abstract. This paper is a review on conics defined by five elements, i.e., either lines to which the conic is tangent or points through which the conic passes. The gallery contains all cases combining a number (n) of points and a number (5-n) of lines and also allowing coincidences of some points with some lines. Points and/or lines at infinity are handled as particular cases.
