• a(1) = 2, a(n+1) is the largest squarefree number < 2*a(n).at n=17A076994
• Primes of the form 1024n + 513.at n=13A105132
• Primes p such that (p+3839)/3840 is also a prime number.at n=4A162141
• Primes formed by concatenating palindromes having even number of digits with 1.at n=27A210534
• Number of n X 2 arrays of the minimum value of corresponding elements and their horizontal, vertical or diagonal neighbors in a random, but sorted with lexicographically nondecreasing rows and nonincreasing columns, 0..2 n X 2 array.at n=32A219810
• Evolution of 13094 using Eric Angelini's add-or-subtract-and-iterate procedure.at n=2A235335
• Primes having only {1, 4, 8} as digits.at n=22A260270
