 A188156 If A187211 is written, starting at its fifth term, as a triangle with rows of lengths 2, 4, 8, 16, ..., the n-th row begins with the first 2^n-1 terms of the present sequence. 1

Sloane, The Toothpick Sequence and Other Sequences from Cellular Automata, Congressus Numerantium, Vol. 206 (2010), 157-191.

Sloane, Catalog of Toothpick and Cellular Automata Sequences in the OEIS Nathaniel Johnston, The Q-Toothpick Cellular Automaton EXAMPLE The triangle from A187211 begins: 22, 20 22, 40, 54, 40 22, 40, 54, 56, 70, 120, 134, 72 22, 40, 54, 56, 70, 120, 134, 88, 70, 120, 150, 168, 246, 360, 326, 136 ... Thus this sequence is 22, 40, 54, 56, 70, 120, 134, 88, 70, 120, 150, 168, 246, 360, 326... The final entry of the n-th row (for n >= 2) is 16 + 8(2^n - 1). CROSSREFS Cf. A147646, A187210, A187211.
