• Binary representation of the middle column of the "Rule 137" elementary cellular automaton starting with a single ON (black) cell.at n=8A267514
• a(n) is the concatenation of a(n-1) and the Hamming distance between a(n-1) and its reverse (i.e., the minimum number of bitflips needed to make them identical). Sequence written in binary.at n=4A274069
• An expanded binary notation for n: the normal binary expansion for n is expanded by mapping each 1 to 10 and retaining the existing 0's.at n=29A304453
