 A337916 Numbers k such that four (or more) consecutive Ramanujan tau numbers are congruent mod 691, or A000594(k) == A000594(k+1) == A000594(k+2) == A000594(k+3) mod 691, or A046694(k) = A046694(k+1) = A046694(k+2) = A046694(k+3). 2

 OFFSET 1,1 COMMENTS The corresponding Ramanujan tau numbers mod 691 are listed in A337917(n) = A046694(a(n)). See A121742 for more information. LINKS Jud McCranie, Table of n, a(n) for n = 1..1419 Eric Weisstein's World of Mathematics, Tau Function. EXAMPLE Ramajuan tau A000594(1045217422) == A000594(1045217423) == A000594(1045217424) == A000594(1045217425) == 269, so 1045217422 is in the sequence. CROSSREFS Cf.
