Appears in sequences

• a(1) = 2; a(n+1) is obtained by writing a(n) in binary and trying to complement just one bit, starting with the least significant bit, until a new prime is reached.at n=27A059459
• Primes that have the property that deleting some digit results in a prime with the same multiplicative order, or period (repeating length of 1/p).at n=2A116074
• Number of arrays of n integers in -5..5 with sum zero and equal numbers of elements greater than zero and less than zero.at n=6A201808
• Number of arrays of 7 integers in -n..n with sum zero and equal numbers of elements greater than zero and less than zero.at n=4A201815
• Triangle read by rows: T(n,k) is the number of weighted lattice paths B(n) having a total of k uhd and uHd strings.at n=45A247294
