%N Largest number in a 6-tuple (a,b,c,d,e,f) of positive integers satisfying the Markoff(6) equation a^2 + b^2 + c^2 + d^2 + e^2 + f^2 = 3*a*b*c*d*e*f.
%H Wikipedia, <a href="http://en.wikipedia.org/wiki/Markoff_equation">Markoff number</a>
%e 2 is in the sequence since (2, 2, 1, 1, 1, 1) is a solution to a^2 + b^2 + c^2 + d^2 + e^2 + f^2 = 3 *a*b*c*d*e*f. 4, 10, and 11 are in the sequence since (4, 2, 1, 1, 1, 1), (10, 4, 1, 1, 1, 1), (11, 2, 2, 1, 1, 1) are solutions with a>=b>=c>=d>=e>=f>=g. This sequence lists the first components among all solutions in increasing order.
