Collecting coeffients in a huge sum...

coefficients grassmann-numbers physics

Note added: Issue resolved, see my comment below.

I have a sum of several thousands addends each of which is the product of a c-number times a product of 6 Grassmann-odd degrees of freedom, the latter of which does each belong to a set of 24 Grassmannians. The specific numbers are not that important, though.

This sum should equal zero. So I would like to add all c-numbers multiplying the same product of six Grassmannians, taking proper care of anticommutativity, of course. The sum would then be zero if all these sums of c-numbers are zero. Unfortunately, using Physics:-Coefficients is far too slow; actually, it has never succeeded in even completing the calculation.

Therefore, I have tried to loop through all the addends, splitting each one of them using selectremove(), and then adding the c-numbers in an Array (properly indexed), or in a table (associatively indexed, of course). Consistently, by converting the Array and table to two sets, the two methods result in the same set of equations. But solving these equations yields a result that is not stable: it varies from session to session.

I am baffled. Can anyone give me a hint to a safe and reasonably quick method for extracting these c-number-valued equations?, for there has to be something wrong with what I do.

Everything is too small...

Hi

Hope somebody can help me! I installed Maple on my computer, but everything is very small , for example the bar in the top with all the small icons. It is the same thing when I make plots. The values on the axes are very small. How can I change this?

I have taken a photo of the problem, don't know if it helps.

Problem in combinatorial geometry...

Let four straight lines in general position be given. Their complement consists of  11 domains. One can choose four (PS. different) points belonging to the pieces s.t. exactly two points lie astride everyone of these lines. Here is an example.

 

restart; with(geometry)``

line(L1, [point(A, 1, 1/2), point(B, 2, 1)]):

geometry:-line(L2, [geometry:-point(C, 1, -1/2), geometry:-point(E, 2, -1)]):

geometry:-line(L3, [geometry:-point(F, 1/2+1, 1), geometry:-point(G, 1+1, 2)]):

geometry:-line(L4, [geometry:-point(H, -1/2+2, 1+2), geometry:-point(K, (-1)+2, 2+2)]):

geometry:-point(P1, [-6, 0]):``

geometry:-point(P2, [2, 6]):

geometry:-point(P3, [8, -6]):

geometry:-draw([L1, L2, L3, L4, P1(color = blue, symbol = solidcircle, symbolsize = 15), P2(color = blue, symbol = solidcircle, symbolsize = 15), P3(color = blue, symbol = solidcircle, symbolsize = 15), P4(color = blue, symbol = solidcircle, symbolsize = 15)])

How many are such configurations (If the points belong to the same pieces, two configurations are equivalent. PS. I.e. one may move points in the  pieces.)?
How to determine it with Maple? Robert Israel used GraphTheory, having answered that.
