Two new gems about nine- and pandigitals !
G. L. Honaker, Jr.
The sum of the first 10701 consecutive prime numbers is a nine digit anagram.
572469138
in Honaker's words pandigital (excluding the zero)
or in Weisstein's words zeroless pandigital.
The sum of the first 32423 consecutive prime numbers
is pandigital.
5897230146
in this case pandigital means including all 10 digits exactly once.
Note that 32423 is the only palindromic prime that produces such a number.
