Which masses placed on a sphere to connect is up to you.  A useful method
that works for arbitrary distributions of points on a sphere is to connect
each mass with its nearest neighbors.  But you have to find the right
number of neighbors to get a stable shape.  In most cases you will best
place an additional mass in the middle and connect all other masses to
this one in addition.
