Super-simple (v, 4, 2) directed designs and a lower bound for the minimum size of their defining set

M. Boostan, S. Golalizadeh, N. Soltankhah

In this paper, we show that for all v\pmod 1 (mod 3), there exists a super- simple (v, 4, 2) directed design. Also, we show that for these parameters there exists a super-simple (v…
