There were many many errors on LucasLehmer sequence on mersennewiki.
I have redefined the sequence by S(0)=4 ( and S(n)=S(n1)^22 ). If you look the proof: 0 is very good starting index for the sequence. From mersennewiki: ""The value of S0 has about 2 (= 2^1) bits "" It means that the starting index is zero! ""LucasLehmer number denoted Sn where S1 = 4 and Sn = (Sn1)^2 − 2 ."" So the starting index is one!! ""So that where S3 = 14, S4 = 14^2  2 = 194, and S5 = 194^2  2 = 37634."" If you define S(3)=14 then S(2)=4, so here the starting index is two!!! So there were 3 definitions for the same Lucas sequence!!! I've corrected these errors.

help on lucas
hi there i just want to ask u all is there any free code for lucas that i can use in cryptography as a tool.
or if u know where to find the source code or the algorithm of it. if u know please just send it to my email (homam.eltaj@gmail.com) yours Homam thanks all

it is useless for any cryptographic purpose. It has no use whatsoever.

Sorry
Sorry but I'm new here i don't know how to use this site
any way thanks a lot and for lucas there is a big usage of it in cryptographic cause I'm working on it and there is a lot more so i just want to make the library of it to be as a tool in program but u know if there is a code of this library i will save time so again if u know the link please just let me know thanks Warmest Regards

may be yes
may be yes iimm talking about the lucas numbers wich they are a part of the Fibonacci because i need to use the set of Lucas in my project and sorry i know that there is some types of Lucas such as the TriLucas and others but i need the basic algorithm of the Lucas to use it as a Library in my Project thats all
thanks a lot yours
