How to create a matrix of values from a single table

$

I'm a real novice user and I we use SQL Server. I have a table called TableLog that has the 4 columns. The first column is repeated x number of times for each value in the second column. I'd like to see this information put into a matrix where I could tell if there are any missing intersections. In addition, I need to insert a WHERE clause that says "BETWEEN 20090000 AND 20100000" for the first and second columns.

Example data in the table:
ID1 ID2 MRSSI
100 200 63
100 300 63
200 100 63
200 300 63
300 100 63

Desired matrix: P = Pass and F = Fail

100 200 300
100 n/a P P
200 P n/a P
300 P F P

From the example data, there's no intersection for 300 and 200 so a F is displayed.

Thx in advance!
