added further explanation

| May 21, 2014 at 19:43 | comment | added | SQB | Could you expand upon your explanation? Right now you're just claiming that this is true, but not proving it. Especially the remark about the parity could use some explanation. Should E1 have been reduced to {3,5} if {2,7} had been in A1, A7, and E7? | |
