Appears in sequences

• Numbers n with property that for each single digit d of n, we can also see the decimal expansion of d+2 as a substring of n.at n=28A135411
• Partial sums of A001394.at n=11A176086
• Reversible primes with k digits, of the form concat(a,b), such that, with all the possible k-1 concatenation of two numbers a and b, we get k-1 primes (a mod b) and the sum of these k-1 primes is a reversible prime itself.at n=11A346559
• Prime numbersat n=26946
