COMMENTS
a(1), a(2) and a(3) were obtained via an exhaustive search; Lower bounds on a(4) through a(10) are 65, 190, 447, 890, 1603, 2675, 4200. - Lieven Clarisse, Jan 29 2017
I moved a(4)-a(6) back to the data field, even though they have not been proved. If they are deleted the sequence melts away. - N. J. A. Sloane, Jan 31 2017
