Abstract :
We give each binary word of length n with p ones, p/n→0, a code whose length asymptotically by 1.56 bits per one exceeds the minimum. The encoding and decoding speed counted in operations over bits is maximal to within a constant factor. So, we trade length for speed. We present similar algorithms enumerating the pyramid and ball cubic lattices
