The solution by @jacobusmmsmit is probably the way to go. For completeness, here’s a way to rewrite your code to be shorter and arguably easier to read:

```julia
julia> combination_vectors(a, b) = vcat(([f s] for f in a for s in b)...)
combination_vectors (generic function with 1 method)

(@v1.7) julia> combination_vectors(a, b)
6×2 Matrix{Int64}:
 1 4
 1 5
 2 4
 2 5
 3 4
 3 5

```
