An efficient orbit to fly a space craft from the L1 lagrange point to mars sun-synchronous orbit?

Hello there everyone,


I joined this competition callled The International Space Settlement
Design Competition organized by Nasa. In the request for proposal of
the
competition that is given to me and my team, they require us to design
a space settlement qthat will be the habitat of 14 000 people orbiting
around Mars.

so can anyone tell me an efficient orbit to fly a space craft from the
L1 lagrange point to mars sun-synchronous orbit?

Thank you.
