The ranges correspond to FFT sizes. > 2. The upper limit is 79,300,000. Again a curious number. > Why this number? 2 to the 26th would be about 67,000,000.

The PrimeNet page only recognises exponents regularly attributed by manual reservation or PrimeNet. The GIMPS page contains results provided by people on exponents that were not (or no more) assigned to them.
