Mar 19, 2016 at 19:17 comment added Dima Pasechnik I presume by self-complementarity you mean that the complement of each block is a block itself. (Like in the design of hyperplanes of an affine space over $\mathbb{F}_2$.)
Mar 19, 2016 at 18:25 comment added Dima Pasechnik Please clarify what exactly you mean by "self-complementary". That the design admits a polarity? Or is isomorphic to the dual (this would be the usual meaning of self-complementary)? Or something else? Or you just mean to say that the block size is half the number of points?
