%U 30,6,30,30,38,42,10,74,34

%N Differences between successive six-digit distinct-digit primes.

%C There are 10238 terms in this sequence, all of which are in the b-file. - _Harvey P. Dale_, Jun 06 2018

%H Harvey P. Dale, <a href="/A074670/b074670.txt">Table of n, a(n) for n = 1..10238</a>

%e a(1)=8 & a(2)=30 because first three 6-digit distinct-digit primes are 102359, 102367, 102397 and differences between them are 8 and 30.

%t a=102345; b=a+8000; se6 = Select[Range[a, b, 2], Length[Union[IntegerDigits[ # ]]] == 6 && PrimeQ[ # ] & ]; Flatten[Table[{se6[[i+1]]-se6[[i]]}, {i, Length[se6]-1}]]

%t Select[Prime[Range[9593,78498]],Length[Union[IntegerDigits[#]]] == 6&] // Differences (* _Harvey P. Dale_, Jun 06 2018 *)

%Y The first differences of A074669. For 3-digit distinct-digit primes, see A074675, A074676. For 4-digit distinct-digit primes, see A074673, A074674. For 5-digit distinct-digit primes, see A074671, A074672. For 7-digit distinct-digit primes, see A074667, A074668. For 8-digit distinct-digit primes, see A074665, A074666.
