Properties

Appears in sequences

• Primes with 23 as smallest positive primitive root.at n=29A061335
• For bases b = 2, 3, ..., n, let the base-b expansion of n be [c_{1,b} c_{2,b} .. c_{r_b,b}], with the most significant "digit" on the left, 0 <= c_{i,b} < b, and c_{1,b} != 0; then a(n) is the number whose base-n expansion is the sum of all those expansions, regarding the c_{i,j} as integers mod n.at n=16A247880
• Expansion of Product_{k>=1} (1 + x^k + x^(3*k)) / (1 - x^k).at n=28A266647
• Primes that are the first in a run of exactly 5 emirps.at n=9A346025
• Prime numbersat n=10142
