This is my last computation (22/11/2012), of first seven decompositions of unit, as sum of Egyptian fractions with n different minimum denominators Xi :

n Xi
3 2,3,6
4 2,4,6,12
5 3,4,5,6,20
6, 2,4,6,14,120,280
7, 2,4,6,16,51,944,6018
8, 2,4,6,16,59,262,17346,102704
9, 2,4,5,26,97,892,9313,1391520,86722657
