While painstakingly trying to build the 600 cell in googlesketch up, using the 24 cell made by rectifying the 16 cell
I check quickfur's site for construction pathways
http://eusebeia.dyndns.org/4d/24-cell
I also checked the old thread I made here
viewtopic.php?f=25&t=1535&p=16064&hilit=600+cell+construction#p16064
Wendy and quickfur mentioned of coherent indexing
When I read the method will give you icosahedra which later form the snub 24 cell, I then tried using the same method on an ordinary octehedra
And then bingo! A nice icosahedron

I then browse google, and notice most method of making a icosahedron is very troublesome
No I can finally make icosahedron in google sketchup and in my drawings
This also make me wonder what happen if I apply the same method to a 16 cell...
->Back to working on the 600 cell
