I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment Make FactorInteger print its result with CenterDot and Superscript?
@user2612743. I'm sorry, but my best advice is not to fix it, but to forget about monkeying with $Preprint (which can have strange side-effects unless you know exactly what you are doing) until you have a much better understanding of how Mathematica works. If you don't understand that HoldFirst is an attribute and not a function and what difference that makes, you are not ready to mess with $Preprint. I do recommend this download if you want to learn more.

Just a couple of ideas. The function you give to $PrePrint doesn't have the HoldFirst attribute and it doesn't return one of the formatted forms, but the evaluated, but unformatted, form of its argument.

What makes you think you have a memory problem? I don't see anything in your question that indicates the file is too big.

I can reproduce your problem, but can't see anything wrong with your code. I suspect a bug in Mathematica's rendering algorithm has surfaced here. Could be wrong because I have little experience with Graph.
