• Numbers k such that three consecutive Ramanujan tau numbers are congruent mod 691, or A000594(k) == A000594(k+1) == A000594(k+2) mod 691, or A046694(k) = A046694(k+1) = A046694(k+2).at n=0A121742
• Least k such that A046694(k) = A046694(k+1) = ... = 0 are n consecutive zeros starting with A046694(k), where A046694 = Ramanujan tau numbers mod 691.at n=2A134670
