 A060924 Bisection of Lucas triangle A060922: odd indexed members of column sequences of A060922 (not counting leading zeros). 11
 3, 7, 6, 18, 38, 9, 47, 158, 120, 12, 123, 566, 753, 280, 15, 322, 1880, 3612, 2568, 545, 18, 843, 5964, 15040, 16220, 7043, 942, 21, 2207, 18342, 57366, 83780, 57560, 16536, 1498, 24, 5778, 55162, 206115 (list; table; graph; refs; listen; history; text; internal format)
 OFFSET 0,1 COMMENTS Row sums give A060927. Column sequences (without leading zeros) are, for m=0..5: A005248(n+1), 2*A061171, A061172, 4*A061173, A061174, 2*A061175. Companion triangle A060923 (even part). LINKS FORMULA a(n, m)=A060922(2*n+1-m, m). a(n, m)=((2*n-m+1)*A060923(n, m-1) + 2*(2*(2*n+1)-3*m)*a(n-1, m-1) + 4*(2*n-m)*A060923(n-1, m-1))/(5*m), m >= n >= 1; a(n, 0)= A0024850(n); else 0. G.f. for column m >= 0: x^m*pLo(m+1, x)/(1-3*x+x^2)^(m+1), where pLo(n, x) := sum(A061187(n-1, m)*x^m, m=0..n+floor((n-1)/2)) are the row polynomials of the (signed) staircase A061187. EXAMPLE {3}; {7,6}; {18,38,9}; {47,158,120,12}; .. pLo(2,x)= 2*(3+x-2*x^2).
