Number of nonnegative integer arrays of length n+2·5-2 with new values introduced in order 0 upwards and every value appearing only in runs of at least 5. A211697

a(n) is the smallest integer that makes A230762(n) the commonest number of decompositions of 2k into an unordered sum of two odd primes, where 3 <= k <= a(n). A230822

Primes having only {0, 4, 8, 9} as digits. A386076

Smallest prime that is the (sum, k·prime(k),k=m,..n+m-1) for some m, or 0 if no such m exists. A268467

a(1) = 5, a(n) = smallest (nontrivial) multiple of a(n-1) containing n digits, a(n) not equal to 10·a(n-1). Also a(n) is not divisible by 10. A80449
