A156117 Smaller of two successive primes using the same digits such that the hundreds digit is the most significant digit to differ. 0

%I #6 Jul 22 2014 22:08:57

%S 48091,64091,116293,139091,145091,162091,244091,250091,276781,321091,

%N Smaller of two successive primes using the same digits such that the hundreds digit is the most significant digit to differ.

%C One of the other two less significant digits (and possibly both) will also differ.

%C Most of the Ormiston prime pairs referenced in A069567 differ only in the two least significant digits.

%e 18379 is not included since the next prime 18397 does not change the hundreds digit even though the same digits are used.

%e 64091 is included because the next prime is 64109 which uses the same digits and the hundreds digit is the most significant digit changed.

%e 29610901 is not included because the next prime is 29611009 which differs in the thousands digit.

%Y Cf. A069567 properly contains this sequence.

%K nonn,base

%O 1,1
