 A296355 True position where binary expansion of n starts in the list of binary numbers in the binary Champernowne sequence A076478. 4

 OFFSET 0,4 COMMENTS A296354(n) is the official position where the binary expansion of n appears in A076478, but the binary expansion of n may also appear earlier, by accident, and it is that starting position that is listed here. In fact every number > 1 appears earlier - see A296356 for the proof. LINKS Rémy Sigrist, Table of n, a(n) for n = 0..16384 Rémy Sigrist, Perl program for A296355 EXAMPLE Here is the list A076478 broken up to show the successive binary numbers (the indexing starts at 0): 0, 1, 0,0, 0,1, 1,0, 1,1, 0,0,0, 0,0,1, 0,1,0, 0,1,1, 1,0,0, 1,0,1, ... 2 = 1,0 officially starts at position 6, so A076478(2) = 6, but 1,0 actually can be seen starting at position 1, so a(2) = 1. 4 = 1,0,0 officially starts at position 22, so A076478(4) = 22, but 1,0,0 actually can be seen starting at position 1, so a(4) = 1.
