OEIS Sequences

Number of labeled graphs with 2-colored nodes where black nodes are only connected to white nodes and vice versa. A47863

Array read by antidiagonals: T(n,k) is the number of graphs on n labeled nodes, each node being colored with one of k colors, where no edge connects two nodes of the same color. A322280

Array read by antidiagonals: T(n,k) = n! * ∑_s 2^{∑_i=1..k-1 s(i}*s(i+1))/(∏_i=1..k s(i)!) where the sum is over all nonnegative compositions s of n into k parts. A361950

Square array T(n,k), n >= 0, k >= 0, read by antidiagonals downwards, where T(n,k) = ∑_j=0..n k^j*(n-j) * binomial(n,j). A355395
