There would be more than 24 sets each using 30 numbers. For example assume the following sets have 30 numbers in sequence ie an increase of 1 from one number to the next number in sequence.

{1...30}, {2...31} {3...32}, {4...33}, {5...34}, {6...35}, {7...36}, {8...37}, {9...38}, {10...39}, {11...40}, {12...41}, {13...42}, {14...43}, {15...44},

{16...45}, {17...46}, {18...47}, {19....48}, {20...49}

If you were to pick numbers 1,2,5,17,30,49 these numbers would not be covered by any of the... [ More ]

Hi, I'm trying so solve following problem:

Let's say, we have a set A={1,2,3,.....49}.

Now, I am defining sets A1, A2, A3,....An as follow: A1={a1,a2,a3,....a30}, A2={b1,b2,b3,...b30}, and so on, where all elements of sets Ai are also elements of set A, which means they are subsets of set A. (All sets Ai have 30 elements).

Now, I am looking for a set C={ {A1},{A2},{A3},....{An} } so, that if I pick randomly 6 elements of set A, they will be (at least) in one of sets Ai.

What is n? Le... [ More ]
