Properties

Appears in sequences

• Triangle read by rows: T(n,k) is the number of unlabeled acyclic digraphs with n >= 0 nodes and n-k outnodes (0 <= k <= n).at n=33A122078
• Numbers k with maximal exponent in prime factorization equal to 1, such that k+1 has maximal exponent 2, k+2 has maximal exponent 3, and k+3 has maximal exponent 4.at n=17A176913
• Primes that cannot become a different prime under any mapping of some single decimal digit <=> with some other single decimal digit.at n=12A180561
• Primes of the form 3*m^2 - 5.at n=27A201717
• Viggo Brun's ternary continued fraction algorithm applied to { log 2, log 3/2, log 5/4 } produces a list of triples (p,q,r); sequence gives q values.at n=32A359743
• Primes having only {4, 7, 8} as digits.at n=33A385795
• Prime numbersat n=8595
