We use the method of spectral networks to calculate BPS degeneracies in the Minahan-Nemeschansky E7 theory, as representations of the E7 flavor symmetry. Our results provide another example of a pattern noticed earlier in the Minahan-Nemeschansky E6 theory: when the electromagnetic charge is n times a primitive charge, the BPS index is a positive integer multiple of (−1)n+1n. We also calculate BPS degeneracies in the Minahan-Nemeschansky E6 theory for larger charges than were previously computed.
