Question:paired sequence in reverse order

Hi,

 

tmp:=seq([phi[5-j]*(1-p[6-j]),phi[5-j]*p[6-j]],j=1..4);
Vector(8,[seq(op(tmp[i]),i=1..4)]);

"tmp" is basically what I want. Some kind of 'paired' terms, indexed in reverse order.

I wonder if there is a better (perhaps more efficient and "direct") way to do it?

 

Thanks,

casper
