4 primes (Posted on 2015-05-06) Difficulty: 3 of 5
There is a prime quadruple i.e. four consecutive primes such that:

a. Each one of them consists of distinct digits.
b. For each one of them the sum of the digits' cubes is a prime number.
c. In the new sequence of 4 primes none has repeated digits.

I believe there is a poor chance of multiple solutions but you are welcome to explore the issue after finding "my" quadruple (all are 3 digit primes).

Solution the finding | Comment 1 of 3
Given criteria a and b and that all four of the consecutive primes are 3-digit primes, it is fairly easy to find that the prime quadruple is:

821, 823, 827, and 829.


83 + 23 + 13 =  521
83 + 23 + 33 =  547
83 + 23 + 73 =  863
83 + 23 + 93 = 1249
Each of 521, 547, 863 and 1249 are prime.
