OEIS Sequences

Triangle T(n,k), n>=1, 0<=k<=n², read by rows: row n gives the coefficients of the chromatic polynomial of the square diagonal grid graph DG_n,n, highest powers first. A212208

Expansion of (1 - x)/(1 + x - 2·x² + x³). A78039

G.f.: 1/(1+x+x³). A199804

Values of n such that L(7) and N(7) are both prime, where L(k) = (n²+n+1)*2^2·k + (2·n+1)*2^k + 1, N(k) = (n²+n+1)*2^k + n. A226927

Narayana's cows sequence: a(0) = a(1) = a(2) = 1; thereafter a(n) = a(n-1) + a(n-3). A930

a(n) = a(n-1) + a(n-3) for n >= 3, with a(0) = 1, a(1) = a(2) = 0. This recurrence can also be used to define a(n) for n < 0. A78012

Expansion of (1-x)³/(1 - 4·x + 3·x² - x³). A52529
