| Apr 25, 2013 at 22:19 | comment | added | Brendan McKay | @Gerhard: Yuichiro is correct. Only row and column sums need to be $k$. | |
| Apr 25, 2013 at 21:08 | comment | added | Yuichiro Fujiwara | @Gerhard I think it means each row and column is of uniform weight $k$. At least the conjecture on Zhan's list considers 0-1 matrices in which every row and column has exactly $k$ 1's. | |
| Apr 25, 2013 at 20:50 | comment | added | Gerhard Paseman | Does line mean one or more of row, column, and diagonal? Also, what recent progress do you mean? Gerhard "Ask Me About System Design" Paseman, 2013.04.25 | |
