Appears in sequences

• Base-4 digits are, in order, the first n terms of the periodic sequence with initial period 1,3.at n=15A037576
• 2nd row of Family 1 "90 X 150 array": generations 0 .. n of Rule 90 starting from seed pattern 7.at n=14A048711
• Decimal representation of n-th iteration of the Rule 54 elementary cellular automaton starting with a single black cell.at n=15A118108
• a(1)=1. For n >= 2, each a(n) = the decimal equivalent of either a(k)U0Ua(k) or a(k)U1Ua(k), where U denotes concatenation of the binary representations of the arguments, and where k is some positive integer < n. The numbers are arranged in numerical order.at n=23A165784
• A249183 seen as binary numbers.at n=15A249184
• Number of (n+3) X (1+3) 0..1 arrays with each row divisible by 15 and column not divisible by 15, read as a binary number with top and left being the most significant bits.at n=27A263119
