• Number of achiral triangular n-ominoes (n-iamonds) (holes are allowed).at n=24A030223
• Primes in which odd positioned digits are composite and even positioned digits are primes. The least significant digit is the taken to be the first digit.at n=34A083821
• Primes with digit sum = 34.at n=23A106769
• a(n) = A107712(n) - A002110(n).at n=4A107964
• Smaller of two consecutive prime numbers such that p0+p1=average of twin prime pairs and p0*p1+7=average of twin prime pairs.at n=6A153374
• Primes that are sum of both three and five consecutive primes.at n=39A211170
• Quadruple Hex-primes: let f(n) = A102489(n); then sequence lists primes p such that f(p), f(f(p)). f(f(f(p))) and f(f(f(f(p)))) are also primes.at n=24A237440
• Number of partitions of n with difference 7 between the number of odd parts and the number of even parts, both counted without multiplicity.at n=44A242698
• Partial sums of the number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 627", based on the 5-celled von Neumann neighborhood.at n=34A273276
