Properties

Appears in sequences

• Numbers k such that k^2 contains only digits {1,5,6}.at n=10A053902
• a(n) = Lucas(n+1) - (n+1).at n=20A066982
• First occurrence prime gaps of the primes in sequence A002313 (Real primes with corresponding complex primes). a(0) = 2 with length of gap 3. For n>0 the size of the gap in the sequence is 4n, a(n) is the starting prime of the gap.at n=32A084160
• Primes that are the sum of two squares and which set a record for the gap to the next prime of that form.at n=13A084161
• Indices of primes in sequence defined by A(0) = 59, A(n) = 10*A(n-1) - 41 for n > 0.at n=24A101581
• Primes p such that q-p = 26, where q is the next prime after p.at n=26A124594
• Primes in A152535.at n=28A152563
• Consecutive Pythagorean primes p = A002144(r) and q = A002144(r+1) such that q - p > log(p)^2. The number a(n) is the n-th value of p.at n=8A216924
• Sequence derived from arithmetic relations between powers of phi (A001622): a(n) = phi^n - (-1)^n * (n - phi^-n).at n=22A248924
• Number of n X 3 0..1 arrays with every element unequal to 0, 2, 3 or 6 king-move adjacent elements, with upper left element zero.at n=21A304136
• Primes p such that neither g-1 nor g+1 is prime, where g is the gap from p to the next prime.at n=40A355485
• a(n) is the smallest prime p such that there are n numbers between p and nextprime(p) which are not prime powers.at n=24A368749
• Prime numbersat n=4164
