Abstract: Pascal's triangle is closely associated with the expansion of the product \((1+x)^n\). We will discuss two analogous arrays of numbers that are associated with the products \(\prod_{i=0}^{n-1} \left(1+x^{2^i}+x^{2^{i+1}}\right)\) and \(\prod_{i=1}^n \left(1+x^{F_{i+1}}\right)\), where \(F_{i+1}\) is a Fibonacci number. All three arrays are special cases of a two-parameter family that might be interesting to investigate further.
