• Triangle T(n,k) of n X n binary matrices with k=0..n^2 ones under action of dihedral group of the square D_4.at n=42A054252
• Floor(exp(n)/n^3).at n=19A132406
• Auxiliary c(n) sequence used to prove some properties about Rowland's sequence. c(n) has the following recursive definition: c(1) = 5, c_(n+1) = c(n) + lfp(c(n)) - 1, where lpf(.) denotes the lowest prime factor of a number.at n=38A190894
• a(n) = Sum_{1 <= i, j, k, l, m <= n} gcd(i,j,k,l,m).at n=8A344524
