Appears in sequences

• Primes that are a concatenation of 5, 7 and a prime.at n=25A101249
• Primes of the form (2^n - 1)*(2^(m+3)) + 5 where n >= 1, m >= 1.at n=15A225214
• Square array A(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of continued fraction 1/(1 - x/(1 - 3^k*x/(1 - 5^k*x/(1 - 7^k*x/(1 - 9^k*x/(1 - ...)))))).at n=31A291261
• Prime p such that the prime before p is a substring of p^3.at n=6A321796
• Square array read by antidiagonals upwards: T(n,k) (for n>1 and k>0) is the smallest k-digit prime p such that prevprime(p) appears as a substring in p^n; or -1 if no such prime exists.at n=19A383613
