How Many Cards Should You Lay Out in Quad-128: A Classification of Caps in AG(7,2)
Karianne Calta, Timothy E. Goldberg, Lauren L. Rose
We define a cap in the affine geometry AG(n,2) to be a subset in which every collection of four points is in general position. In this paper, we classify, up to affine equivalence,…
