Properties

Appears in sequences

• Number of stacks, or planar partitions of n; also weakly unimodal compositions of n.at n=24A001523
• a(n) is the least prime beginning with prime(n) such that the concatenation a(1)a(2)...a(n) is a prime.at n=13A090510
• Bisection of A001523.at n=12A100505
• Primes p such that p^2 - 8, p^2 - 6 and p^2 - 2 are prime.at n=18A176960
• Primes having only {0, 3, 4} as digits.at n=15A199340
• Let an integer with k+1 digits as n = d(k)*10^k + d(k-1)*10^(k-1) + ... + d(0)*10^0 and consider the transform T(n) = k*10^d(k) + (k-1)*10^d(k-1) + ... + 0*10^d(0). a(n) gives the fixed points of the transform T(n).at n=38A226767
