Code details

best found code with parameters
q=11 k=3 n=77
minimum distance = 69

this is new optimal code


the previous bounds were -1/69
this is a projective code


We used the prescribed group of automorphisms with the following generators


4 0 0
0 6 0
0 0 10

10 0 0
0 10 0
0 0 10

This group makes 29 orbits of sizes:

1 1 5 5 1 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5


The solution of the corresponding linear system of equations was found after less than 10 seconds:

0 1 0 0 1 1 0 1 1 1 0 1 0 1 1 1 1 0 0 1 0 1 1 0 0 1 1 0 1 7 6 8 7 1 8 8 6 7 6 8 7 0 6 7 8 7 8 8 7 8 7 6 7 8 7 8 7 8


This produces the following generator matrix

0 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10
