I present results from my attempt to nest 5-arm star C and D arrays
in between the existing A,B and E arrays of Helfer 2003 for the
purpose of simplifying the required road and cable trenches for the
more compact arrays. We have generated C and D arrays that uses the
existing A,B and E array pads, and places the other pads needed for C
and D arrays within the confines of a 5-arm star with arms of width
10 metres. The beam properties are respectable, but the overall
result is that there are too many constrained parameters for our
beams to be competitive unless the cost savings are significant.
These configurations save money by populating the entire set of
5 configuration with just 51 antenna pads and may significantly
simplify the road and cable trenching  requirements in the inner
few hundred metres. The savings need to be assessed in more detail.
