Code details

best found code with parameters
q=13 k=3 n=79
minimum distance = 72

this is new optimal code


the previous bounds were -1/72
this is a projective code


We used the prescribed group of automorphisms with the following generators


12 0 0
0 12 0
0 0 12

2 2 2
0 2 2
0 0 2

This group makes 15 orbits of sizes:

13 13 13 13 13 13 13 13 13 13 13 13 13 13 1


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

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


This produces the following generator matrix

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