Some Optimal Codes From Designs %K Optimal code %K t-design %R %X The binary and ternary codes spanned by the rows of the point by block incidence matrices of some 2-designs and their complementary and orthogonal designs are studied. A new method is also introduced to study optimal codes. %U http://bims.iranjournals.ir/article_353_1c31d56b10fe384966174ee83e0eb049.pdf
