Hi. I have the following problem: consider the following list of compositions and its cartesian product with itself.
C83=Compositions(8, length=3); cp=CartesianProduct(C83,C83) I want to remove certain elements from this set/list and then to count the elements left. For example I want to remove the element [[1,1,6], [1,2,5]] and in general for [[a,b,c],[d,e,f]], I want to remove it if a=d=1 OR b=e=1 Or c=f=1. There are other things I want to remove but I think if I figure out the correct syntax for the above I could probably figure the rest out. How would I do this? thanks for the help. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
