I have seen Primussupremus's first googolism defined using his notation, which gave me a great idea. I will define BIG FOOT Primussupremus.0 below using his notation. Note: This is just for fun, I already know that this is a salad and that it doesn't improve BIG FOOT by any significant amount.
{BIG FOOT, BIG FOOT, BIG FOOT| BIG FOOT, BIG FOOT#BIG FOOT}.
Edit: LOL, I have no idea how his notation works but I know it will easily beat his Ternarygollumtree. Credit for the array notation goes to Primussupremus.
