Finding switches to do this would just suck.
Most home switches are 8 port. So if you buy 9, 8 port switches and one 16 port 10 gig switch plug 7 in each of the first 9 switches that would get you to 63 that would leave one to plug into the hub. Plus each 8 port would need to be gig unless you can buy switches with single gig.
or 4, 16 port gig switches with a ten gig uplink to a 10 gig switch any way you need enough to plug in all 64 +1 for the head node. any which way this is a switching nightmare. The head node needs a 10 gig so that it can handle all 64 nodes at 100 mbps. Each set of 8 gets close to a gig network traffic for the head node. so 64 nodes is 6400 mbps that is why I say 10 gig. Maybe I'm missing something but it seems complicated.
