Properties

Appears in sequences

• a(n) = ceiling(n*phi^19), where phi is the golden ratio, A001622.at n=4A004974
• Numbers k such that the continued fraction for sqrt(k) has period 83.at n=32A020422
• Concatenation of prime p and nextprime(p) is prime -> cycles of 2 steps possible.at n=11A036339
• Numerators of continued fraction convergents to sqrt(599).at n=8A042148
• Discriminants of real quadratic fields with class number 1 and related continued fraction period length of 23.at n=37A051964
• Primes p that have exactly three primitive roots that are not primitive roots mod p^2.at n=17A060519
• List of Ormiston prime pairs.at n=17A072274
• Primes p such that p's set of distinct digits is {3,7,9}.at n=25A108385
• Antidiagonal triangular matrices of factorials as the example: M(3)={{0, 0, 1}, {0, 1, 2}, {1, 2, 6}}; the matrices are used to get characteristic polynomials and the triangular sequence is the coefficients of those characteristic polynomials.at n=31A137296
• a(n) is the least k such that the period of the decimal expansion of 1/k is A000204(n).at n=18A173491
• Primes with nine embedded primes.at n=19A179917
• Largest prime with n nonprime substrings (substrings with leading zeros are considered to be nonprime).at n=3A213301
• Prime(k), where k is such that (1 + Sum_{i=1..k} prime(i)^19) / k is an integer.at n=15A233769
• Primes which are the concatenation of two primes in exactly three ways.at n=11A238499
• Super-prime leaders: right-truncatable primes p with property that appending any single decimal digit to p does not produce a prime.at n=12A239747
• Primes of form n^2 + 28561.at n=15A256841
• Primes having only {3, 7, 9} as digits.at n=44A260382
• Prime numbersat n=3960
