[seqfan] Re: nXn Binary Matrices Squared Still Binary

Without further conditions on the matrix entries in the title of A122527,
isn't it a generalization that the number of k X n binary matrices is equal
to just 2 ^(k*n), so that A122527(1) = 2^7 = 128, hence the sequence does
not match the definition, or have I missed something (as usual)?
