If a requirement were added that reverse(p) also be a prime, the result would be sequence A343715. %e A343714 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). %e A343714 31513 is a term in two ways: as the concatenation 3//151//3 and as the concatenation 31//5//13. %e A343714 7392937 is a term in three ways: 7//39293//7, 73//929//37, and 739//2//937. %Y A343714 Cf.
