How to Create FULLER43H: Fuller Mixed Aperture 4,3 Hexagonal Grid?

[RMWinslow]

The vignette lists FULLER43H as an available grid., which alternates between apertures 3 and 4. However, the documentation for the dgconstruct function doesn't mention the possibility of a mixed aperture.

aperture | How finely subsequent resolution levels divide the grid. Options are: 3, 4. Not all options work with all projections and topologies. Default: 3

Is there a command allowing for the creation of a Fuller hex grid with mixed aperture 4,3?
Or is the vignette in error listing this grid as available?
