Properties

Appears in sequences

• Primes p such that the Fibonacci iterations starting with (1, p) lead to a "nine digits anagram".at n=13A034588
• Numerators of continued fraction convergents to sqrt(643).at n=7A042234
• Number of n X n binary arrays symmetric under 180 degree rotation with all ones connected only in a 11100-00100-00111 pattern in any orientation.at n=12A147254
• Primes of the form 10n^2 + 3.at n=25A201710
• Always start on the lowest digit of a(n), then visit all digits of a(n) in increasing order. The terms of the sequence are the smallest one that force the visitor to walk n steps to complete his tour (a single step drives you from a digit to the closest one).at n=11A336611
• Prime numbersat n=9768
