You need to try a little harder on these.There are 9 slots to be filled. There are 11 integers that could be used.There are (119) ways to choose the set of integers usedIt's clear the order these have to be placed. Except that either arrangement in the vertical blocks can be used. That gives us an additional factor of 4n=(119)4=220
