| Abstract: | We show that the automorphism group of a divisible design  is isomorphic to a subgroup H of index 1 or 2 in the automorphism group  of the associated constant weight code. Only in very special cases H is not the full automorphism group. |
| Keywords: | Divisible design constant weight code automorphism group |
