The parameter p
By choosing the parameter "p" in the main window of DISCRETA, you have several possibilities:
If you have prescribed the symmetry group of a solid as automorphism group, and calculated designs with this group, you can visualize the design no. p by the chosen solid.
On the other hand, if you want to run the isomorphism test by p-Sylow subgroups (described here), choose a prime p which looks sensible, i.e. fairly large prime divisor of the group order of the chosen automorphism group.
