Reconstruction of group multiplication tables by quadrangle criterion

Group Theory 2007-05-23 v1 Combinatorics

Abstract

For n>3n>3, every n×nn\times n partial Cayley matrix with at most n1n-1 holes can be reconstructed by quadrangle criterion. Moreover, the holes can be filled in given order. Without additional assumptions, this is the best possible result. Reconstruction of other types of multiplication tables is discussed.
