I have the following table of bitmasks (this is a fraction/sample of the actual table. The data I am working with has many more bitmask columns).

bm1    bm2    bm3
-------------------------
0      0      0
1      0      0
0      2      0
0      0      4

I would like to do a CROSS JOIN (of sorts) to list all possible combinations. But I would like the results to be in rows, not columns. Like this:

bm1    bm2    bm3
-------------------------
0      0      0
0      2      0
0      0      4
1      0      0
1      2      0
1      0      4
0      2      4
1      2      4

The order of the columnar data must persist. i.e. bm1 can only be a 0 or 1, bm2 can only be 0 or 2, and bm3 can only be 0 or 4, etc.

Also, I am not committed to the original table of bitmasks. If there is a better approach to produce the desired resulting data, I am open to it.

How can this be accomplished?
Thank you!
