Code details

best found code with parameters
q=11 k=3 n=43
minimum distance = 38

this is new optimal code


the previous bounds were -1/38
this is a projective code


We used the prescribed group of automorphisms with the following generators


0 0 10
10 0 0
0 10 0

10 0 0
0 10 0
0 0 10

10 0 0
0 10 0
0 0 10

This group makes 45 orbits of sizes:

3 3 1 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3


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

0 0 1 0 0 0 0 0 0 0 1 0 0 0 1 1 0 1 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 1 1 1 0 0 0 1 0 1 1 1 1 5 5 0 5 5 5 5 4 5 5 4 4 2 4 5 4 5 0 5 5 4 5 4 4 5 3 4 5 5 5 5 5 4 4 0 0 5 2 4 4 5 4 2 2 0


This produces the following generator matrix

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

Which is a code with the following weight distribution
1y43+630x38y5+420x39y4+30x40y3+120x41y2+130x43
