OEIS Sequences

Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(0) + b(1) + ... + b(n-1), where a(0) = 1, a(1) = 2, b(0) = 3, and (a(n)) and (b(n)) are increasing complementary sequences. A295053

Primes having only {0, 1, 5} as digits. A199325

Base-6 pandigital primes: primes having at least one of each digit 0,1,2,3,4,5 when written in base 6. A175278

Primes in carryless arithmetic mod 10 in which all digits except the rightmost are zero or five. A169984

Primes p with p + 2, prime(p) + 2 and prime(prime(p)) + 2 all prime. A236481

Expansion of e.g.f. T(x) satisfying T(x) = (1/2) * sinh( 2·x*cosh( x·sqrt(1 + 4·T(x)²) ) ), where a(n) is the coefficient of x^2·n+1/(2·n+1)! in T(x) for n >= 0. A372814

Primes of form n.0.n+1, where '.' represents concatenation. Or, primes of form 10^k+1*n + n + 1, where k is the number of digits in n. A96525

Let p run through the primes; write p in base 10 and then interpret it in base 128 getting a number q; if q is prime then adjoin q to the sequence. A90718
