One occurrence of "more than 1 time" should be "more than once" as elsewhere.

Can you do a round of pep8 formatting?

I would use lamda as an alternate name for lambda (since lambda is a reserved keyword in Python). I find it makes code easier to read than lambd or lmbda.

• Property Summary changed from Addition of some difference matrices and all related objects to Combinatorial designs: add some difference matrices and related objects
• Property Milestone changed from sage-9.1 to sage-9.2
 initial I added a few constructions of difference matrices whose \lambda parameter is not 1. I then modified the orthogonal arrays and transversal designs constructions to take advantage of my additions. Finally, I added a new function symmetric_net. We add a few constructions of difference matrices whose lambda parameter is not 1. We then modify the orthogonal arrays and transversal designs constructions to take advantage of these additions. Finally, we add a new function symmetric_net.
