%N Palindromic primes of the form p//q//reverse(p), where p, q, and reverse(p) are primes.
%C If reverse(p) were allowed to be nonprime, the result would be sequence A343714, which includes such terms as 19391.
%e 353 is a term because it is a palindromic prime (A002385) and is the concatenation of 3 (a prime), 5 (a palindromic prime), and 3 (the reverse of 3, and also a prime).
%e 31513 is a term in two ways: as the concatenation 3//151//3 and as the concatenation 31//5//13.
%e 7392937 is a term in three ways: 7//39293//7, 73//929//37, and 739//2//937.
%Y Cf. A002385, A045336, A177678, A343714.
