Given the 7-element set   A = { a,b,c,d,e,f,g }. Find a collection  T  of 3-element subsets of  A  such that each pair of elements from  A  occurs exactly in one of the subsets of  T.

We can make $T$ by taking two disjoint $3$ elements subsets of A.

Eg. T={{$a,b,c$},{$d,e,f$}} but we cannot include all the elements.
