For example, when calculating A066411(5), I observed that the sums from 56 through 104 (49 of the 61 sums) were contiguous.  As I have calculated the values of A066411, I have also tracked the size of this central contiguous zone.   Interestingly, the vast majority of sums stein this zone, except for n=4 and n=6.
