ach team must have an odd number of Masters, and any two teams must have an even number of Masters in common....
$begingroup$
The Jedi Council is forming assault teams. Each team must have an odd number of Masters, and any two teams must have an even number of Masters in common. Show that the number of different teams cannot be larger than the size of the Council.
The problem can be solved using Linear Algebra. A hint was given to encode the teams as elements of $mathbb{F}^n$ where $mathbb{F} = mathbb{Z}_2$. Show that the teams are independent using the dot product and argue using dimension. Any ideas?

Number the masters from $1$ to $n$. Then encode a team as a vector where component $k$ is $1$ if and only if master $k$ is on the team.

Makes sense. I will try that. Thank you.
