• Indices of primes at which the prime race 4k-1 vs. 4k+1 is tied.at n=24A038691
• Odd numbers with exactly 4 distinct palindromic prime factors.at n=21A046406
• Consider all integer triples (i,j,k), j >= k > 0, with i^3 = binomial(j+2,3) + binomial(k+2,3), ordered by increasing i; sequence gives i values.at n=20A054208
