What is the command to summon the biggest slime in minecraft?

I want to summon the biggest slime but I forgot how to do it.

Make sure cheats are enabled, and type this command:

/summon Slime x y z {Size:size}

x, y, and z are the coordinates where you want to spawn the slime. This is optional (if left blank, the slime will spawn at the position of the player). size is the size of the slime.

Examples:

/summon Slime {Size:50}             spawns a slime of size 50 at your position
/summon Slime 2 10 -224 {Size:1}    spawns a slime of size 1 at the point (2, 10, -224)

The biggest slime you may spawn is of Size:256. You may check the page on Slimes if this is true or not. So, if you want to summon the Slime at it's largest size, you would type:

/summon Slime x y z Size:256

If I'm not wrong.
