Properties

Appears in sequences

• Consider all integer triples (i,j,k), j,k>0, with i^3=j^3+binomial(k+2,3), ordered by increasing i; sequence gives k values.at n=20A054236
• Primes p equal to the sum of two successive sexy primes - 1 such that p - 6 is also prime.at n=31A104047
• Centered triangular numbers that are prime.at n=29A125602
• Partial sums of A102659 read as decimal integers.at n=9A135255
• Primes p such that the multiplicative order of 2 modulo p is (p-1)/11.at n=9A152311
• Number of arrays of -3..3 integers x(1..n) with every x(i) in a subsequence of length 1 or 2 with sum zero.at n=8A193643
• Primes of the form 3*m^2 - 8.at n=16A201781
• Numbers k such that the periodic part of the continued fraction of sqrt(k) has more ones than any smaller k.at n=36A206579
• Primes p such that b=2*p+1 is semiprime, c=2*b+1 is 3-almost prime and d=2*c+1 is 4-almost prime.at n=23A235646
• Number of partitions of n which have nonconstant reversal sums, as defined in Comments.at n=37A236170
