yes basically, but why can there not be maps of non-planar graphs?

Plane Map <=> Planar Graph ?? Hi, Wondering if anyone can help me to find some kind of proof that all Plane Maps can be represented by planar graphs and vice versa... for all Planar Graphs exists a Plane Map? I did a quick search without much luck. Thanks

Schneier's book doesn't tell you why the systems are used that way, infact it just tells you in a rather coarse way to "do this and do that"... Try "Modern Cryptography: Theory and Practice" by Wenbo Mao or "Cryptography" by Nigel Smart for a more mathematical look on crypto.

Hi, I am intrigued at how this is almost proven on a computer? Since you have to test all the even integers to infinity, I am assuming you guys are almost at infinity? As for the last line of hey. like's post I have a screen shot... http://www.jiangmao.plus.com/avatars/final_lines.jpg

I was revising for my ALevel P6 exam the other day and I came up against a very tough question... I can do parts i and ii axa = x^-1, let x = e a^2 = e a = a^-1 for part ii axa = x^-1 axax = e axax(ax)^-1 = (ax)^-1 //ax and (ax)^-1 will cancel ax = (ax)^-1 but for part iii and...
