i. Let the minimum support be 10. How many distinct aggregate cells will there be like the following:
{(a1, a2, a3, a4, . . . , a99, ∗) : 10, . . . , (a1, a2, ∗, a4, . . . , a99, a100) : 10, . . . , (a1, a2, a3, ∗, . . . , ∗, ∗) :
10}?
There will be 2101 − 6, as shown above.
ii. If we ignore all the aggregate cells that can be obtained by replacing some constants by ∗’s while
keeping the same measure value, how many distinct cells are left? What are the cells?
There are only three distinct cells left: {(a1, a2, a3, . . . , a100) : 10, (a1, a2, b3, . . . , b100) : 10, (a1, a2, ∗, . . . , ∗)
