A234020 Offsets from the middle point of each row of A233270 to the nearest point containing a maximum value of that range. 6

%N Offsets from the middle point of each row of A233270 to the nearest point containing a maximum value of that range.

%C Please see the graph of A233270. Iff a(n)=0, A234018(n) = A234019(n).

%C Seems to grow faster than A233274. Is the ratio a(n)/A233274(n) converging to some limit?

%o (Scheme)

%o (define (A234020 n) (let ((middle (A233268 n))) (let loop ((i middle) (m 0) (maxp middle)) (cond ((zero? (A233270 i)) (- middle maxp)) ((> (abs (A233270 i)) m) (loop (- i 1) (abs (A233270 i)) i)) (else (loop (- i 1) m maxp))))))

%Y Cf. A233268, A233270, A234018, A234019, A233274.
