Let A be the incidence matrix of a finite projective plane of order 10.
Let V be the vector space generated by the rows of A over ,
the finite field with two elements {0,1}. A vector in V is called a
codeword. The weight of a codeword is the number of 1's in the
codeword. Let be the number of codewords of weight i. We define
the weight enumerator of V to be
