| Abstract: | It is shown that among all Preparata codes only the code of length 16 is distance regular. An analogous result takes place for Preparata codes after puncturing any coordinate (only the code of length 15 is distance regular). |
| Keywords: | Preparata codes perfect codes distance regular codes automorphism groups of codes |
