• a(n) = (11*n + 5)^2.at n=38A017450
• a(n) = (12*n + 3)^2.at n=35A017558
• The periodic point counting sequence for the toral automorphism given by the polynomial of (conjectural) smallest Mahler measure. The map is x -> Ax mod 1 for x in [0,1)^10, where A is the companion matrix for the polynomial x^10+x^9-x^7-x^6-x^5-x^4-x^3+x+1.at n=47A059928
• Squares n^2 that become prime after omitting all ones in their decimal expansion.at n=12A175983
• Squares whose arithmetic mean of digits is 6 (i.e., the sum of digits is 6 times the number of digits).at n=4A316486
• E.g.f. A(x) satisfies A(x) = A(x^3)^(1/3) * exp(3*x) with A(0)=1.at n=8A374347
• Square numbers whose iterative sums of digits are squares.at n=42A384296
• Powers k^m, m > 1, odd k that are neither squarefree nor squareful.at n=27A392423
