✦ Synopsis


The connection between maximal caps (sometimes called complete caps) and certain binary codes called quasi-perfect codes is described. We provide a geometric approach to the foundational work of Davydov and Tombak who have obtained the exact possible sizes of large maximal caps. A new self-contained proof of the existence and the structure of the largest maximal nonaffine cap in PG(n, 2) is given. Combinatorial and geometric consequences are briefly sketched. Some of these, such as the connection with families of symmetric-difference free subsets of a finite set will be developed elsewhere.

An asymmetric binary covering code of length n and radius R is a subset C of the n-cube Q n such that every vector x 2 Q n can be obtained from some vector c 2 C by changing at most R 1's of c to 0's, where R is as small as possible. K þ ðn; RÞ is defined as the smallest size of such a code. We show

We study a vertex operator algebra whose Virasoro element is a sum of pairwise 1 orthogonal rational conformal vectors with central charge . The most important 2 example is the moonshine module V h . In particular, we construct a series of vertex operator algebras whose full automorphism groups are

## Abstract We introduce the following new viewpoint in the study of caps in PG(__m__,__q__). The objective is to maximize, among all caps of given cardinality in a given projective space, the number of free pairs of points, which we define as pairs of points not participating in any coplanar quadr
