In particular, we here give a link to a file with all optimal binary codes of length 8, covering radius 2, and size 12. These codes are available here. The format of the file is as follows. The first line gives the number of codes (277). For each of these codes, the following lines are included: 1) the size of the automorphism group, 2) the number of codewords (always 12), 3)-14) the codewords in decimal form.
