diffhist Bruck–Ryser–Chowla theorem 15:43 +134 Will Orrick talk contribs (I would prefer to use the notation (v,k,lambda)-design rather than (v,b,r,k,lambda)-design, but I can't find anywhere the former is used in Wikipedia, so I've left it as is. Instead, I've moved the word "symmetric" to the opening sentence and added a bit more information about how the parameters relate in the symmetric case. I also added math templates in the opening paragraph.)
