Actually I understand the first part of the question which says, how many ways can you partition a set of six elements. This is just done with a bell number. It is the second part which says "into 3 blocks" that I do not understand. {124; 5; 36} This is three blocks. 124 is a block 5 is a block and 36 is a block. As you questioned, 124 means 1,2,4.
