Here we ask to get a(10), the
first unknown term for
by Dmitry Kamenetsky.
Smallest k such that k! can be represented as the sum of the
n-th powers of two or more distinct primes; or -1 if no such
2, 4, 8, 10, 12, 15, 19, 20, 24, 25
This means to
get the minimal k! such that it is equal to the sum of the 10th power of
two or more distinct primes.
It has been proved that a(10)>26
