%N a(n) = first of exactly n consecutive integers that each divide A181063(n).

%C a(n)=1 iff n belongs to A181062.

%C A181063(n) = lcm(a(n) .. a(n)+n-1).

%e The discrete string of 5 consecutive integers that divide A181063(5)=3960 begins with 8 and ends with 12; hence a(5)=8.

%Y Cf. A181062, A181063.

%K nonn

%O 1,5
