Continuity mistake: While receiving the prime number pulses, there is a discontinuity between the pulse sequence being received and what is displayed on the monitors. As the sequence for "seven" starts (right after Ellie tells Fish to start counting the pulses), the camera switches to a computer monitor display which indicates the sequence for "seven" has already completed, and is logging the pulses of the sequence for "eleven".
