Finite-field Kakeya set
= Finite-field Kakeya set
A subset of $\mathbb F_q^n$ is a finite-field Kakeya set when it contains an <affine line in a vector space> in every one-dimensional direction. The line position may depend on the direction. The <polynomial method in combinatorics> yields the <finite-field Kakeya polynomial bound> on its <cardinality>.
