Properties

Appears in sequences

• Numbers n such that n is a substring of its square in base 8 (written in base 10).at n=17A018832
• Prime number spiral (clockwise, West spoke).at n=25A054570
• Primes of the form 6n^2 - 1.at n=24A090686
• Least initial value for a Euclid/Mullin sequence whose 3rd term (= least prime divisor of 1+2p) equals the n-th prime. prime(1)=2 is never a third term, so offset=2.at n=42A094464
• Floor (e^(n / log(n))).at n=34A096181

• Inverse Euler transform of A005169 (fountains of coins).at n=23A226999
• Primes having only {0, 2, 3, 6} as digits.at n=29A386043
