COMMENTS

There are exactly 97 three-digit primes with all distinct digits, so the sequence is finite.

EXAMPLE

a(1)=4 because the first and the second three-digit primes with all distinct digits are 103, 107 and difference between them is 4.

MATHEMATICA

se=Select[Range[103, 983, 2], Length[Union[IntegerDigits[ # ]]]==3&&PrimeQ[ # ]&]; Flatten[Table[{se[[i+1]]-se[[i]]}, {i, 96}]]
