The first occurrence of a chain of six successive
near-repdigit primes: 199, 211, 223, 227, 229, 233. [Beedassy]
The lesser of the smallest emirp pair (199, 991) each of
whose members is the sum of a prime number of consecutive
primes in a prime number of different ways: (199 = 61 + 67
+ 71 = 31 + 37 + 41 + 43 + 47) ; (991 = 191 + 193 + 197 +
199 + 211 = 127 + 131 + 137 + 139 + 149 + 151 + 157). [Beedassy]
