• a(n) = n^5 + 1.at n=21A002561
• Sum of distinct powers of 20; i.e., numbers with digits in {0,1} base 20; i.e., write n in base 2 and read as if written in base 20.at n=33A063012
• Let the binary expansion of n be [b_d, b_{d-1}, ..., b_3, b_2, b_1, b_0]_2, where (if n>0) b_d = 1, b_i = 0 or 1 for i<d. To get a(n) concatenate the decimal numbers 2^(b_i) (if b_i = 1) or 0 (if b_i = 0).at n=33A302205
