Erasure codes have profound uses in wide- and medium-area storage
applications. While infinite-size codes have been developed with
optimal properties, there remains a need to develop small codes with
optimal properties. In this paper, we provide a framework for
exploring very small codes, and we use this framework to derive
optimal and near-optimal ones for discrete numbers of data bits and
coding bits. These codes have heretofore been unknown and
unpublished, and should be useful in practice. We also use our
exploration to make observations about upper bounds for these codes,
in order to gain a better understanding of them and to lead the way
for future derivations of larger, optimal and near-optimal codes.
