SUMMARY
The discussion focuses on calculating the number of elements of order 4 in the symmetric group S6. The key forms identified are the 4-cycles (abcd) and the 4+2 cycles (abcd)(ef). With a total of 720 elements in S6, the calculation begins by selecting 4 elements from 6, which is a combinatorial problem. The distinct 4-cycles can be derived from the permutations of the chosen elements, leading to a systematic approach for counting both pure 4-cycles and 4+2 cycles.
