The fact that four is cosmic, at least in English, is quite well discussed.
However, what if we instead took a number and then took the first letter of its word form that number and converted it to its alphabetical placing to generate a sequence?
Your job is to:
1) Find three numbers which generate its own cyclic sequence.
2) Even more special, find the number which just repeats itself. (i.e. the cosmic number of this sequence)
3) Any other cyclic number(s) that I may have missed (or a 'proof' that there are no others).
