Below are shown four groups of symbols, only one of which is correct. One group, when inscribed on the blank square, will open the lock that secures the great door.

Study the symbols carefully and compare them with the other three groups in the illustration accompanying entry 131. When you think you have found the group of symbols that completes the sequence of four, turn to the entry given below it:

If you believe A completes the sequence, turn to 216.

If you believe B completes the sequence, turn to 344.

If you believe C completes the sequence, turn to 42.

If you believe D completes the sequence, turn to 169.
