Task
Find all the non-negative integers up to and including a given non-zero positive integer n, that are prime and the count of
1's
and0's
in their binary representation (having no leading zeroes) are prime too.
Here are the first five such primes,
17, 19, 37, 41, 79
10001, 10011, 100101, 101001, 1001111
Clarifications and rules
- Default I/O methods are accepted.
- The answer can be a program or a function.
- If there are no such primes then output garbage or nothing.
- Standard loopholes are forbidden.
2 3 5 7
did not make it to the list because in their binary representation number of occurrences of0's
and1's
are not prime. Consider7
whose binary representation is111
, here0
occurs zero times and zero is not prime.Built-ins are allowed.
The shortest code in bytes wins!

1You ask for all primes under a given n, but you also say inclusive. Which do you mean? – Riley – 2017-01-16T21:02:54.583
@Riley What I mean is ...
all the numbers from 1....n
. I do not know how to rephrase it in a simple way. – Gurupad Mamadapur – 2017-01-16T21:12:26.780I have phrased it for you. – Jonathan Allan – 2017-01-16T21:13:58.830
@JonathanAllan Thanks a lot. – Gurupad Mamadapur – 2017-01-16T21:14:13.247
6OEIS A144214 – mbomb007 – 2017-01-16T21:16:56.423
3@mbomb007 Clearly, for any total ordering of integer sequences, the smallest uninteresting integer sequence would be itself interesting, and thus worthy of inclusion in OEIS. Ergo, OEIS contains all integer sequences, of any interest real or imagined :-) – Iwillnotexist Idonotexist – 2017-01-16T21:44:19.957
Does the resulting list have to be sorted? – mbomb007 – 2017-01-16T21:54:06.527
@mbomb007 nope. – Gurupad Mamadapur – 2017-01-16T21:57:43.350
9I'm wondering whether Mathematica contains more builtins than OEIS has sequences... – Neil – 2017-01-17T00:48:13.847
