%F a(n) = A268674(A269379(n)).
%F Other identities. For all n >= 1:
%F a(2n) = 2n. [Fixes the even numbers.]
%e For n=9 we first find what number is below 9 in square array A255127, which is 19, then we find what number is above 19 in square array A083221, which is 17, thus a(9) = 17.

%Y Inverse: A269355.
%Y Cf. A268674, A269379.
%Y Cf. also arrays A083221 & A255127.
%Y More recursed variant: A269358. Cf. also permutations A266646, A255408, A269172.
