• Number of classes created in S_n by the {132, 231}{213, 312}-equivalence.at n=11A222319
• Numbers n such that n+k-1 is the sum of two nonzero squares in exactly k ways for all k = 1, 2, 3.at n=6A273318
• Let n be even; m = n/2 and p a prime such that p<=m with n-p nonprime. The sequence contains the successive positive maxima of values n with L = primepi(m-1)-primepi(p+1)> 0.at n=21A293858
