Properties

Appears in sequences

• Values of transition of A072608(n) from alternating behavior (0,1,0,1,..) into steadily-1 (1,1,1,..) behavior or changing back. Expressing in terms of A072609(n): at n values it switches from steadily 0 into steadily 1 successive values or back.at n=19A072610
• Smallest n-digit member of A087593. Define dd(k) = the number formed by concatenating the absolute difference of successive digits of k. Sequence contains smallest n-digit prime p such that dd(p) is also prime.at n=4A087595
• Numbers k such that prime(k) == -6 (mod k).at n=4A092048
• a(n) is the largest number m such that m = pi(n*m).at n=11A102281
• Terms in A006512 containing the digit "6" at least once, such that changing every "6" to a "9" and vice versa yields a larger term in A006512.at n=18A123211
• Primes less than 1000000 sorted lexicographically in decimal representation.at n=30A210761
• Prime values of pi(n) that divide n.at n=10A256394
• Numbers k such that floor(prime(k)/k) < floor(prime(k+1)/(k+1)).at n=19A308082
• Numbers k such that k = PrimePi(k * digsum(k)).at n=3A353126
• Prime numbersat n=9621
