Code details

best found code with parameters
q=13 k=3 n=118
minimum distance = 108

this is new optimal code


the previous bounds were -1/108
this is a projective code


We used the prescribed group of automorphisms with the following generators


0 0 12
12 0 0
0 12 0

9 0 0
0 3 0
0 0 9

This group makes 21 orbits of sizes:

3 6 4 12 12 12 12 12 12 12 12 6 12 4 12 6 12 4 6 6 6


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

0 1 0 1 1 1 0 0 1 1 0 1 0 0 1 1 1 1 0 1 1 10 7 10 10 10 9 10 8 9 10 9 9 10 0 10 10 9 10 9 5 9


This produces the following generator matrix

0 0 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 0 0 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 0 0 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 0 0 12 12 12 12 0 0 12 12 12 12
