[HTML][HTML] On the classification of semifield flocks

A Blokhuis, M Lavrauw, S Ball - Advances in Mathematics, 2003 - Elsevier
… A flock F of K is a partition of K ⧹{v} into q n conics. If all the planes that contain a conic of the
flock share a line then the flock is called linear. Let v be the point … On non-hyperelliptic flocks

On the sporadic semifield flock

… When q is even, all semifield flocks are linear [8]. When q is odd, in … linear flocks, two infinite
classes of semifield flocks are known: the Kantor semifield flocks [14] and the Ganley flocks [7…

A new semifield flock

L Bader, G Lunardon, I Pinneri - Journal of Combinatorial Theory, Series A, 1999 - Elsevier
flock of K for which the planes of the q conics all contain a common point, is of the type just
described ([19]). The flock is called the Kantor semifield flock. … flock F( f, g) is a semifield flock if …

Searching for semifield flocks

I Pinneri - Discrete mathematics, 2002 - Elsevier
… The main result of this paper is: In PG(3,27) any semifield flock is isomorphic either to the
linear, Kantor–Knuth or Ganley flock. No new semifield or likeable flocks have been found. …
