%N Variant of A332563 - binary version of Recamán concatenation sequence.
%C Inspired by Neil Sloane's presentation at Rutgers' Experimental Mathematics Seminar (see the Links section).
%C In the original version (A332563), for a given n, one concatenate the binary representation of n||n+1||n+2||...||n+i until the corresponding number is divisible by n+i+1.
%C In this variant, one skips n+1 as an ingredient of the concatenation.
%C A337137(n) records the least i such that n||n+2||n+3||...||n+i is divisible by n+i+1.
%C This version is tamer than the one in A332563.
%C The scatterplot graph shows some interesting structures.
