Abstract

An (s,t)(s,t)-spread in a finite vector space V=V(n,q)V=V(n,q) is a collection F\mathcal F of tt-dimensional subspaces of VV with the property that every ss-dimensional subspace of VV is contained in exactly one member of F\mathcal F. It is remarkable that no (s,t)(s,t)-spreads has been found yet, except in the case s=1s=1. In this note, the concept αα-point to a (2,3)(2,3)-spread F\mathcal F in {V=V(7,2)V=V(7,2)} is introduced. A classical result of Thomas, applied to the vector space VV, states that all points of VV cannot be αα-points to a given (2,3)(2,3)-spread F\mathcal F in VV. {In this note, we strengthened this result by proving that} every 6-dimensional subspace of VV must contain at least one point that is not an αα-point to a given (2,3)(2,3)-spread of VV.
