• Numbers k such that 2^k ends in k.at n=8A064541
• a(2) = 36; for n >= 3, a(n) = 2^a(n-1) mod 10^n.at n=8A109405
• a(n) is the smallest number k such that k and 2^k have the same last n digits. Here k may have fewer than n digits and can be padded with leading zeros (cf. A121319).at n=9A113627
• a(n) is the smallest number k such that k and 2^k have the same last n digits. Here k must have at least n digits (cf. A113627).at n=9A121319
• a(n) = 2^^(n+2) modulo 10^n, where ^^ denotes a power tower (see A133612).at n=9A206636
