Elementary particle sudoku

well, i missed my blog's official three year anniversary (march 5) and i'll have to blame it on the flu. everything is blamed on the flu when you have the flu. to celebrate, try solving the physics sudoku that i find deep in my computer and probably have already posted a long time ago. it's from symmetry magazine, and the directions are as usual with sudoku only now we've got a 16x16 grid (for 16 elementary particles - the gluons are unified in one category as are the W+ and W-). funfunfun.
