• Let A(n) = #{(i,j,k): i^2 + j^2 + k^2 <= n}, V(n) = (4/3)*Pi*n^(3/2), P(n) = A(n) - V(n); A000092 gives values of n where |P(n)| sets a new record; sequence gives A(A000092(n)).at n=24A000413
• The non-common part of the larger number of an amicable pair.at n=32A180327
• Number of terms of A368917 less than 10^n, where A368917 lists the numbers k for which there is no prime p such that p^p divides the arithmetic derivative of A276086(k), where A276086 is the primorial base exp-function.at n=4A368919
