Let F be a flock of the quadratic cone Q: X 2 2 =X 1 X 3 , in PG(3, q), q even, and let 6 t : X 0 = x t X 1 + t 1ร2 X 2 + z t X 3 , t # F q , be the q planes defining the flock F. A flock is equivalent to a herd of ovals in PG(2, q), q even, and to a flock generalized quadrangle of order (q 2 , q).

โฆ Synopsis
An infinite family of q-clans, called the Subiaco q-clans, is constructed for q = 2 ~. Associated with these q-clans are flocks of quadratic cones, elation generalized quadrangles of order (q2, q), ovals of PG(2, q) and translation planes of order q2 with kernel GF(q). It is also shown that a q-clan, for q = 2 ~, is equivalent to a certain configuration of q + 1 ovals of PG(2, q), called a herd.

In PG (3, q), q even, Cherowitzo made a detailed study of flocks of a cone with a translation oval as base; also called -flocks . To a flock of a quadratic cone in PG(3, q), q even, there always corresponds a set of q#1 ovals in PG(2, q), called an oval herd. To an -flock of a cone with an arbitrary
This article gives a complete classification of even order flocks of oval cones that admit linear doubly transitive automorphism groups. The main theorem shows that the only possible even order examples are the linear flocks, the translation oval flocks of Thas and the Betten-Fisher-Thas-Walker floc
This paper is a contribution to the classification of ovoids. We show, under some rather technical assumptions, that if an ovoid of PG(3, q) has a pencil of monomial ovals, then it is either an elliptic quadric or a Tits ovoid. Further, we show that if an ovoid of PG(3, q) has a bundle of translatio

If F is a flock of the quadratic cone K of PG(3, q), q even, then the corresponding generalized quadrangle S(F) of order (q 2 , q) has subquadrangles T 2 (O), with O an oval, of order q. We prove in a geometrical way that any such T 2 (O) has spreads S consisting of an element y โ O and the q 2 line
