Code details

best found code with parameters
q=11 k=3 n=56
minimum distance = 50

this is new optimal code


the previous bounds were -1/50
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 0 0 0 0 1 1 1 0 0 0 0 1 1 1 1 0 0 1 0 1 1 0 1 0 0 6 0 5 5 1 6 6 5 5 6 5 6 6 6 6 5 6 5 6 6 0 5 5 6 6 5 5 0 6


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

Which is a code with the following weight distribution
1y56+660x50y6+550x51y5+10x55y1+110x56
