In this paper it is shown that given a non-degenerate elliptic quadric in the projective space PG(2n -1, q), q odd, then there does not exist a spread of PG(2n -1, q) such that each element of the spread meets the quadric in a maximal totally singular subspace. An immediate consequence is that the c

Abstract
The functions a(n) and p(n) are defined to be the smallest integer λ for which λ‐fold quasimultiples affine and projective planes of order n exist. It was shown by Jungnickel [J. Combin. Designs 3 (1995), 427–432] that a(n),p(n) < n^10^ for sufficiently large n. In the present paper, we prove that a(n),p(n) < n^3^. © 2001 John Wiley & Sons, Inc. J Combin Designs 9: 182–186, 2001

## Abstract The sporadic complete 12‐arc in PG(2, 13) contains eight points from a conic. In PG(2,__q__) with __q__>13 odd, all known complete __k__‐arcs sharing exactly ½(__q__+3) points with a conic 𝒞 have size at most ½(__q__+3)+2, with only two exceptions, both due to Pellegrino, which are comp
