Permutation of Letters

Character placement EMMA is investigating the number of different letters in her name; she is the same as her friend LUCY. The arrangement of LUCY is twice that of EMMA, they are interested in why this is the fact, and we decided to look up other names and find the answer. Lucy, lucy, luyc, lycu, lyuc, lcyu, lcuy, ulcy, ulyc, uylc, ucly, Ucyl, EMMA - emma, eamm, emam, aemm, amme, amam, meam, maem, mame, mema, mmea, mmea, cluy, clyu, culy, cuyl, cyul, cylu, yluc, yulc, yulc, yucl, yclu, ycul, [IMAGE] 24 [IMAGE]
In my post, I explained that my sentence was inspired by people who were able to combine 26 letters of alphabet and literary magic placement and combination. They use these for words, make sentences, ties them, and it will become a story that leads us into their world, their thoughts and experiences. I applied this feature to Anna's post and Kira's answer and proposed the next 4 x 4 grid or "lighting landscape". The ends of the two axes represent the ends of two continuums. To some extent, this solves Kira's view that "there is no creativity in the vacuum, all art and writing have a relationship between subjective self and subjective environment."
For this purpose, we discuss the fields of mathematics in combinatorics, in particular placement and combination. Line up the number of calculations in which the order in which you count is important. On the other hand, if the number of calculation order does not matter, combine the number of calculation results. We will further subdivide placement and combination and consider whether to replace the option to allow duplicate selections with the selection of the available options after each selection (this concept has "repeat" and "replace" - this week use I replace it. "I will explain each scenario this week.
Arrangement is not particularly interesting. The initial displacement table is described in the schedule IP. The line list is actually a list, but it is displayed as an array for space reasons. The list index of any entry in the displayed table is obtained by adding the displayed row index and column index. If the input data is in boolean array input 1..64, for each bit j (1 ≤ j ≤ 64) of the input, the result of the sort is the t th step. Let Lj and Rj be the right half of the left Tj. Therefore, for Lj = T1t2t3Lt32 and Rj = t33t34t35 Lt64, Tj = LjRj. Lj is calculated from the results of Lj = Rj -1 and Rj = Lj 1. Rj -1, K j () where f is a complex complex function that performs extended shift permutation substitution operation K. It derives from key, but Boolean XOR function
