Rock Paper Scissors SPOCK Lizard

Sorry Sheldon, but it should be 

Rock Paper Scissors Spock Lizard,


Rock Paper Scissors Lizard Spock.

Here is Sheldon Cooper explaining the game:

In the original Rochambeau we have the simple rules:
Rock crushes Scissors
Scissors cut Paper
Paper covers Rock
Which we can represent as:
Rock < Paper < Scissors < Rock
where greater-than "<" represents the win/lose relationship
loser < winner
and Rock is repeated to complete the circular relationship. 

If we call this game "Rock Paper Scissors Spock Lizard" then we can write the rules like this:
Rock < Paper < Scissors < Spock < Lizard < Rock < Paper
now with Rock and Paper repeated (or just understand that it "wraps around"), and the additional rule that any sequence of three (with wrapping) is also a rule.
Rock Paper Scissors
Paper Scissors Spock
Scissors Spock Lizard
Spock Lizard Rock
Lizard Rock Paper
And now the rules are the same as the name of the game.
