It can be
argued
that every positive integer n has an associated prime
curio.
The
reverse
can also be argued.
Regardless, there are a number of curious numbers related to primes.
We call such numbers
``Prime Curios!''.
Some of the curious numbers below have been submitted
and entered into the
``Prime

1613 is a prime such that the previous two primes AND the next two primes are twin primes
There are 1613 prime sextuplets (p, p+4, p+6, p+10, p+12, p+16 all prime) < 10^{10}
1613 is the 17th prime in the prime sequence f(n)=4*n^{2}  4*n + 653
Note that f(0), f(1), ... , f(16), f(17), f(18) are all primes, while f(19) is not.
(760*10^{1613}  31)/9 = 8 repeat(4,1613) 1 is prime
Note the 1613 consecutive 4 preceded by an 8 and followed by a 1
given p2=1613 and the previous prime p1=1609 it is curious that p1^{2} + p2^{3} ± 1 is a twin prime pair
82^{1613}  81^{1613} is prime
1613 is the smallest 4 digit prime that starts a run of 6 consecutive primes where between primes exactly one digit changes and where the resulting digits may be permuted
I.e., 1613, 1619, 1621, 1627, 1637, 1657
1613 is the largest prime factor of 2^{26}+1
π(1613) = 2^{8}1
π(1613) + 2*1619 is a perfect square of a prime

repeat(v, n) = v{repeated n times}
For example:
repeat(309,4) = 309309309309
If can be shown that:
repeat(v, n) = v * (10^{(d*n)}1)/(10^{d}1)
where ''v'' is ''d'' digits in length.
You can use the
calc
program to compute the decimal values of the
above curious numbers.
The following calc function may be used for the repeat(v, n) function:
/*
* repeat  depeat a set of digits
*
* given:
* v digit set to repeat
* n repeat count
*/
define repeat(v,n)
{
local digcnt;
digcnt = digits(v);
return v * (10^(digcnt*n)1) / (10^digcnt1);
}
