Hi,
in this challenge very interesting, the solution has a length limit to 30 in the HTML source.
In the grid of 200, each element of the cluster counts for 6 (x,y xxxyyy as example). Also the limit of the solution is a cluster of size 5 ?
Only, I made a program which often found some clusters of size 8. In this case, the length of the solution is 8 x 6 = 48 ???
Can you explain it ?
Thanx
