OEIS Sequences

Smallest number k such that n! - k is a square. A66857

From fundamental unit of Z[ (-d)^1/4 ], where d runs over positive integers not of the form 4·k⁴. A6828

The distance between n! and the nearest perfect square. A260374

Start to read the sequence digit by digit and erase the first "1" you encounter, then the first "2", the first "3", etc., until the first "9"; go on from there and erase again the first "1", the first "2", etc., until "9" -- and so on, cyclically until the end of the (infinite) sequence. Concatenate what is left. The result is the concatenation of all integers of the sequence. A108709

a(n) = 3n³ + 2n² + n + 1. A130884

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n-k+1), where k = [ n/2 ], s = (F(2), F(3), F(4), ...), t = A014306. A25110

Least number k >= 0 such that n! - k is a perfect power. A240940

10 - Mod(prime(n),10) when prime(n) + 22 = prime(n+1). A74879
