• Define the generalized Pisot sequence T(a(0),a(1)) by: a(n+2) is the greatest integer such that a(n+2)/a(n+1) < a(n+1)/a(n). This is T(8,16).at n=12A018922
• a(n) = 3*a(n-1) - 4*a(n-3) + a(n-6).at n=11A019493
• Numbers k such that k^2 and k^3 have the same set of digits.at n=29A029797
• Numbers whose base-5 representation contains exactly three 0's and three 2's.at n=25A045187
