%N Starts of runs of 3 consecutive Moran numbers (A001101).

%H Amiram Eldar, <a href="/A334371/b334371.txt">Table of n, a(n) for n = 1..10000</a>

%e 3031 is a term since 3031/(3+0+3+1) = 433, 3032/(3+0+3+2) = 379 and 3033/(3+0+3+3) = 337 are all primes.

%t moranQ[n_] := PrimeQ[n / Plus @@ IntegerDigits[n]]; m = moranQ /@ Range[3]; seq = {}; Do[If[And @@ m, AppendTo[seq, k - 3]]; m = Join[Rest[m], {moranQ[k]}], {k, 4, 10^6}]; seq

%Y Subsequence of A001101, A085775 and A154701.

%Y Cf. A235397, A334346.
