7^139 and 7^141 terminate.

Terminates:
13^91 with a p6.
13^93 (not by me).

All is done.
Thank you !

Note : As for me, I have completed the calculations for n=2^478, terminate with a p28.

The calculations become very long for these great powers of 2 !

Dropping all reservations, in order to clean FDB´s composite list.

Drop 12^73

Drop 12^77

Drop 12^79

No pretesting done on these numbers.

Sorry, I can't do anything right now, FactorDB doesn't work normally ! I will try again in a few days...
