Properties

Appears in sequences

• Numbers that are the sum of 12 positive 10th powers.at n=16A004812
• tan(tan(arcsinh(x)))=x+3/3!*x^3+41/5!*x^5+1187/7!*x^7+62129/9!*x^9...at n=4A012162
• Strobogrammatic primes: the same upside down (calculator-style numerals).at n=19A018847
• Numbers k such that the continued fraction for sqrt(k) has odd period and if the last term of the periodic part is deleted the two central terms are both 19.at n=24A031607
• Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,4,2).at n=12A078948
• Primes that become squares when prefixed with a 7.at n=4A167740
• For a lesser p of twin primes, let B_(p+2) and B_p be sequences defined as A159559, but with initial terms p+2 and p respectively. The sequence lists p for which all differences B_(p+2)(n)-B_p(n)<=6.at n=26A276848
• Lesser of twin primes P(k) and P(k+1) such that Sd(P(k)) + Sd(P(k+1)) = Sd(k) + Sd(k+1), where Sd(x) is the sum of digits of x.at n=11A277111
• Primes equal to a centered 9-gonal number plus 1.at n=27A285812
• Prime numbers in A317298.at n=38A306362
