Encoder pulses per revolution

How many pulses does the encoder push out on the A and B channels for each revolution of the motor. I am interested in purchasing the Lynxmotion 12V 10 rpm 776.34oz-in 1:264 Brushed DC Gear Motor w/ Encoder.

There are 16 pulses (north south poles) per rotation of the rear shaft.
Therefore one rotation of the output shaft would have 264 times this number, or 4224 pulses.
