Trinomial TriangleThe trinomial triangle is a number triangle of trinomial coefficients. It can be obtained by starting with a row containing a single "1" and the next row containing three 1s and then letting subsequent row elements be computed by summing the elements above to the left, directly above, and above to the right:
(OEIS A027907). 
The plot above shows the binary representations for the first 255 (top figure) and 511 (bottom figure) terms of a flattened trinomial triangle. See alsoCentral Trinomial Coefficient, Pascal's Triangle, Trinomial, Trinomial CoefficientExplore with Wolfram|Alpha
