determinant

i have another one

To calculate the determinant of the following matrix, I would like to ask is it possible to eliminate any lines,because I don't see how..
and calculating the determinant without elimination is kinda painful.

Re: determinant

Of course!
I would recommend cofactor expansion along (row or column) (3 or 4).
This will leave only two 3x3 determinants to calculate.

Re: determinant

Re: determinant

I don't know but these links should give you some guidance:
Skew-symmetric matrix
Pfaffian

If the solution can't be determined from that second link (good one, by the way), then there might be no hope!
