Abstract: Tight 2 s $2 s$ 2 s -designs are the 2 s $2 s$ 2 s - ( v , k , λ ) $(v, k, \lambda )$ left parenthesis v comma k comma lamda right parenthesis designs whose sizes achieve the Fisher type lower bound ( v s ) ${v \choose s}$ StartBinomialOrMatrix v Choose s EndBinomialOrMatrix . Symmetric 2 $2$ 2 -designs, the Witt 4 $4$ 4 - ( 23 , 7 , 1 ) $(23, 7, 1)$ left parenthesis 23 comma 7 comma 1 right parenthesis design and the Witt 4 $4$ 4 -
