Hello all, I am running the code in the example in Section 9.2 of the GRAPE manual ( http://www.maths.qmul.ac.uk/~leonard/grape/manual/CHAP009.htm) , which generates the Haemers partial geometry pg(4,17,2).
All works well but I cannot understand where exactly the incidence matrix is stored and how to access it. The manual (referred to above) says that there is a *delta* associated to the geometry output by the function PartialLinearSpaces but I can't find it. I tried to run RecNames on the output (the variable called *haemers*) and got this: [ "names", "group", "order", "representatives", "isSimple", "isGraph", "schreierVector", "adjacencies" ] No sign of *delta* and apparently no incidence matrix. Any help will be greatly appreciated. Thanks, Felix -- ---------------------------------- Felix Goldberg, Ph.
