I want to solve the following problem:

Print  (a, b, c, d, e, f, g, h)

this  should satisfies

1, a,b,c,d,e,f,g,h are integers  from -10 to 10

2, a+b+c+d+e+f+g+h=4 and a+2b+3c+4d+6e+8f+12g+24h=24

Please help me.

Thank you very much.

Hi, I want to print     t[n] / (-1)^n * sum   as following, but I don't know where the error is. Please help me.

Thank you very much.

I have a question:

let t(n)=sum( (binomial(n,j))^4, j=0..n )  , t(-1)=0, t(0)=1

and (n+1)^3 *t(n+1)=(2n+1)*(a*n^2+a*n+b)*t(n)+n*(c*n^2+d)*t(n-1)             (1)

I want to Print(a,b,c,d) so that t(n) satisfies the recurrence relation (1)  where a,b,c,d are integers and their ranges are from

-30 to 30.

Please help!

Here is a relation: t[n+1]:=((a*n^2+a*n+b)*t[n]+c*(n^2)*t[n-1])/(n+1)^2

t[-1]:=0 and t[0]:=1

a,b,c are integers and a,b,c are from 1 to 20 and n is from 0 to 20

the series t[n+1] is integer

I want to know how to list (a,b,c) that satisfies the above. Please help!
