Difficult)))
cruel and annoying notation to memorize. I struggled so hard to see how (14)(13)(12) = (1234) until I wrote it out in the original notation of permutations and did the composition...but that is hard to make the transition. would have been easier to start with this new notation...
I was really confused if the book meant to say transposition on page 233 instead of transformation...in the paragraph under the bolded heading "The Alternating Groups"...they have not said anything about what a transformation is...??
Transformation is not in the book defined...I'm pretty sure they used the wrong word...annoying to read a defective text...
Reflective)))
the factorization of permutations is either even or odd...just like integers are even or odd. Number theory permeates all of math!!
