Properties

Appears in sequences

• a(n) is the n-th prime whose decimal expansion begins with the decimal expansion of n.at n=32A077345
• Ordered hypotenuses of primitive Pythagorean triangles having legs that add up to a square.at n=23A088319
• Let p run through the primes; write p in base 10 and then interpret it in base 128 getting a number q; if q is prime then adjoin q to the sequence.at n=11A090718
• Balanced primes of order ten.at n=18A096702
• Larger prime in pair prime(k) +/- k for some k.at n=39A107637
• Primes p such that there exist three primes q, r and s with p^3=q^3+r^3+s^3.at n=35A114923
• Erroneous version of A100200.at n=16A151996
• Binary transpose primes. Integers of k^2 bits which, when written row by row as a square matrix and then read column by column, are primes once transformed.at n=41A155967
• Coefficient of x in the reduction by x^2->x+1 of the polynomial p(n,x) defined at Comments.at n=15A193049
• Unique terms in sequence A210144.at n=41A214196
• Primes whose binary reversal is a square.at n=28A226019
• Numbers n such that (2^(2n+7) * 5^(2n+5) + 740711) / 33 is prime (n > 0).at n=6A260903
• Smallest number k with A355915(k) = n.at n=37A356792
• Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n*k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of internal vertices in the resulting planar graph.at n=50A367303
• Prime numbersat n=3554
