The first occurrence of a twin prime pair (6089, 6091) that both consist of a nonprime number of nonprime digits only. Note that the larger member is an invertible prime which turned upside down corresponds also to the larger member (1609) of a twin prime pair. [Beedassy]

The smallest circular-digit prime that contains all circular digits. [Loungrides]
