The generalized Hosoya triangle is an arrangement of numbers in
which each entry is a product of two generalized Fibonacci numbers. We
prove the GCD property for the star of David of length two. We give
necessary and sufficient conditions such that the star of David of
length three satisfies the GCD property. We propose some open questions
and a conjecture for the star of David of length bigger than or equal
to four. We also study GCD properties and modularity properties of
generalized Fibonacci numbers.
