• Expansion of (1 - 3*x - x^2)/(1 - 4*x + 2*x^3 + x^4).at n=10A195350
• Number of (n+7)X11 0..1 matrices with each 8X8 subblock idempotent.at n=6A224593
• Number of (n+7) X 14 0..1 matrices with each 8 X 8 subblock idempotent.at n=3A224596
• Define a set of generalized Syracuse sequences starting with x(1)=2*n+1 a positive odd integer, if x(i) is odd prime set x(i+1)=67*x(i)+1, if x(i) is odd not prime set x(i+1)=3*x(i)+1 and if x(i) is even then set x(i+1)=x(i)/2. Then a(n) is the first index i > 1 at which x(i) reaches 1.at n=29A300286
