Code details

best found code with parameters
q=16 k=3 n=52
minimum distance = 48

this is new optimal code


the previous bounds were -1/48
this is a projective code


We used the prescribed group of automorphisms with the following generators


15 0 0
0 15 0
0 0 15

12 2 2
7 7 7
2 9 10

This group makes 7 orbits of sizes:

51 51 51 51 17 51 1


The solution of the corresponding linear system of equations was found after less than 500 seconds:

0 0 0 0 0 1 1 0 4 4 4 4 4 0


This produces the following generator matrix

0 0 0 0 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15 15
