comment What all all possible summes that yeild number N called
My next question was going to be is there any relation to Primes and Partitions -- just saw there is a lot of work in that area :-) -- I wish I had majored in Math.

comment Understanding a plot of composite numbers against the ordinal position of their prime factors
Many thanks for the answer Robert -- I'll comeback and try to digest the answer in a bit -- you have to forgive me my math brain cells have been receding for a while

@RobertIsrael -- yes to " 5, 35 and 52, not 11, 140 and 229?" -- I just realized my question text was wrong -- corrected -- thanks

@RobertIsrael so the y axis the the order of the prime like 2 is 1, 3, is 2, ..., 11 is 5, 149 is 35, etc. -- I'll update the question with this clarificaiton

Hi @RobertIsrael, I was trying to get the lines to be as linear as possible so I was trying to pick a ration and I tried E/PI and it seemed to get me the most linear graph.

mmm good point. I'll do that in a bit.

well yeah that's where the idea grew from, if you mean RSA

@Ethan I've edited my LaTeX, is the question any clearer now?

comment Using Prime numbers to map n integers uniquely to an integer x and allowing an easy reverse mapping
I want the function to take n integers, say 5, 6 and 21 and give me one number, say X. The caveat being that there should be simple reverse function that will take X and give me 5, 6, 21

Hi, no not homework. Though I was thinking of opening the textbooks of my youth. How much my mind has decayed!
