• Numbers k such that 2^k ends in k.at n=4A064541
• Numbers n such that n and 2^n end with the same 5 digits.at n=9A067869
• a(2) = 36; for n >= 3, a(n) = 2^a(n-1) mod 10^n.at n=4A109405
• 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=5A113627
• 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=5A121319
• a(n) = 2^^(n+2) modulo 10^n, where ^^ denotes a power tower (see A133612).at n=5A206636
• a(n) = (n^2 - n + 2) * (5*n^2 - 5*n + 2) / 4.at n=29A380353
