Abstract
Let An be the set of n X n zero-one matrices satisfying the matrix equation
A
2 = Jn; where Jn is n X n matrices of all ones. In this article, it is proved that the
number of non-isomorphic left loops of order k gives the lower bound to the size of An
for n = k
2. Mainly we have established that any matrix in An corresponding to loop has
rank 2k - 2, where n = k
2, for some positive integer k.
