| 8 | In the same ticket, we will include some of the known non existence of transversal designs: |

| 9 | - The [http://en.wikipedia.org/wiki/Bruck%E2%80%93Ryser%E2%80%93Chowla_theorem Bruck Ryser Chowla Theorm] gives the non-existence of many TD(n+1,n) |

| 10 | - C. Lam in Lam, "The Search for a Finite Projective Plane of Order 10" (1991) proved that TD(11,10) cannot exist |

| 11 | - there is some work (?) that shows that if $k$ is large enough then the existence of TD(k,n) implies the existence of TD(n+1,n) and so the non-existence results can percolate downwards in k |
