comment Reduce the output from tuples by including symmetry?
@j-- That solution is close, it keeps a few that I'd consider redundant and is also missing (at least) one array: {{0, 0, 0}, {0, 1, 0}, {0, 0, 0}}

Sorry about the ambiguity regarding "permutations." I'm not sure the most accurate way to describe it. Imagine taking a 3x3 array of 1's and iteratively changing each 1 to a 0 until you have an array of 0's. I consider a duplicate being an array that is identical under any rotation or mirror around any row or diagonal. j--'s solution is pretty close, although it still misses some. For example, if you do the following command (just to visualize it) you'll see that the 2nd and 5th arrays are the same. ArrayPlot[#, ImageSize -> 20, Mesh -> All] & /@ t3
