Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

COMMENTS

Cf. A052019 Sum of digits of prime p is substring of p.

LINKS

Table of n, a(n) for n=1..28.

EXAMPLE

31513 is OK because its digit sum 13 is a substring of 31513.

MATHEMATICA

bb={}; Do[id=IntegerDigits[p=Prime[n]]; If[StringCount[ToString[p], ToString[Plus@@id]]>0&&Reverse[id]==id, AppendTo[bb, p]], {n, 1000000}]; A109208=bb
