Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%E It would be good to have a set of generators (e.g. a MAGMA program to produce this code).
%E It would be good to also have the weight distribution of the dual code.
