OEIS Sequences

Numbers n such that n1024 + 1 is prime (a generalized Fermat prime). A57002
Sum of numbers in the n-th antidiagonal of the reciprocity array of 0. A259574
Expansion of ∏k>=1 (1 + x2·k-1)k*(3·k-2)*(1 + x2·k)k*(3·k+2). A294841
Numbers whose digits are a permutation of (0,...,m) for some m. A199168
Starting with a(1) = 0, a(2) = 1, a(n) = smallest nonnegative integer that shares all digits with previous terms. No repeated digits are allowed. A297062
Always start on the lowest digit of a(n), then visit all digits of a(n) in increasing order. The terms of the sequence are the smallest one that force the visitor to walk n steps to complete his tour (a single step drives you from a digit to the closest one). A336611
Positive numbers k such that k and 2·k are anagrams in base 6 (written in base 6). A23064
Positive numbers k such that k and 3·k are anagrams in base 6 (written in base 6). A23065
Number of n X 3 arrays of the minimum value of corresponding elements and their horizontal, vertical, diagonal or antidiagonal neighbors in a random, but sorted with lexicographically nondecreasing rows and columns, 0..1 n X 3 array. A219349
Let an integer with k+1 digits as n = d(k)*10k + d(k-1)*10k-1 + ... + d(0)*100 and consider the transform T(n) = k·10d(k) + (k-1)*10d(k-1) + ... + 0·10d(0). a(n) gives the fixed points of the transform T(n). A226767
