%N a(n) = lcm_{i=1..n} A001177(i); partial LCM-products of Fibonacci entry points.

%C From n=3 onward it seems that lcm_{i=1..n} A001175(i) = 2*a(n).

%F a(1)=1, and for n > 1, a(n) = lcm(A001177(n), a(n-1)).

%F a(n) = lcm_{i=1..n} A001177(i). [the least common multiple of all terms from A001177(1) to A001177(n)]
