%N Molien series for 16-dimensional group of structure Z_2^4.S_3 and order 96, corresponding to complete weight enumerators of Hermitian self-dual GF(4)-linear codes over GF(16) containing the all-ones vector.

%E There were errors in the definition (in the order and structure of the group). The Molien series was correct, but to make it easier to check I replaced the formulas with Maple code. Thanks to _Georg Fischer_ and _Andrey Zabolotskiy_ for noticing that something was wrong. - _N. J. A. Sloane_, Jan 29 2021
