This site is supported by donations to The OEIS Foundation.

 Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing. Other ways to donate

 OFFSET 1,1 COMMENTS There is no further term up to 115000000. - Farideh Firoozbakht, Jan 01 2007 a(13) > pi(10^15). [From Donovan Johnson, May 08 2010] LINKS EXAMPLE Prime(968819) = 14968819 which ends in 968819, so 968819 is a term of the sequence. MATHEMATICA (*returns true if a ends with b, false o.w.*) f[a_, b_] := Module[{c, d, e, g, h, i, r}, r = False; c = ToString[a]; d = ToString[b]; e = StringLength[c]; g = StringPosition[c, d]; h = Length[g]; If[h > 0, i = g[[h]]; If[i[[2]] == e, r = True]]; r]; Do[If[f[Prime[n], n], Print[n]], {n, 1, 10^6}] CROSSREFS Corresponding primes are in A046883. Cf. A046883, A068575, A075902.
