Welcome to the Icosahedral Server
Have you ever constructed an icosahedron from a hexagonal paper template? Creating such a model is very beneficial in understanding
viral symmetries, and the core differences between T numbers.
For this reason we have created the icosahedral server to aid you in the construction of your own icosahedron.
A T=3 icosahedron is shown to the left, built with the hexagonal templates found here.
The hexamers (the polygons with 6 sides) denoted by the blue lines are left as-is on the hexagon sheet. The green
lines are found within the units representing pentamers, and are generated by
folding and cutting the paper template. Icosahedrons with any T numbers (T=h**2+h*k+k**2, see
paradigm section) can be generated using this server. The output of the program found here can be either
an ODL file, so that the 3D model can be viewed by O, or a postscript file,
so that a projection of the model (as shown here) can be printed out. These
files can be downloaded directly from this site. By the time you have finished browsing this server, you
will have learned a great deal about the quasi-equivalences of viruses.
