• Sum of distances between greatest-part-order and length-order of partitions of n.at n=17A036051
• Numbers k such that both the k-th and (k+1)-th primes have the same sum of digits squared but different sets of digits.at n=13A109183
• Numbers n with the property that it is possible to write the base 2 expansion of n as concat(a_2,b_2), with a_2>0 and b_2>0 such that, converting a_2 and b_2 to base 10 as a and b, we have antisigma(a) + antisigma(b) = n.at n=9A259670
• Indices of 0 in A348295: numbers m such that Sum_{k=1..m} (-1)^(floor(k*(sqrt(2)-1))) = Sum_{k=1..m} (-1)^A097508(k) = 0.at n=38A348299
