Skew room squares exist for all odd values greater than 5. If n is prime it is a simple matter to generate a skew starter. But 667 is not prime. 667=23*29 which means a computer search has to be...

Taking the square root(s) of binary symmetric matrices would help me with my search for unresolved symmetric balanced incomplete block designs. I have no idea how to do this especially with large...

The square root of a 31 by 31 matrix with 6"s down the main diagonal and 1"s elsewhere is a symmetric binary matrix with six 1's in each row and column. If someone has an algorithm for this square...

I am interested in proving that the incidence matrix M for any symmetric balanced incomplete block design can be written in a manner where M equals M transpose. If so then the incidence matrix...
