COMMENTS

Two consecutive primes that use the same digits (rearranged) are called an Ormiston pair (see A072274).
The first case of three Ormiston pairs in the same century is (65150713, 65150731), (65150737, 65150773), (65150779, 65150797). The definition is unclear in such cases. The linked table includes both 65150713 and 65150737. - Jens Kruse Andersen, Jul 22 2014
