See those two pins? Well today I'm going to... stick them in you.


Ok, let me come clean: Mr.Wizard is actually an alias of mine... I'm glad I can finally confess. ― Sjoerd C. de Vries

No, I'm Spatac... I mean, Mr.Wizard! ― R.M

I'm Mr.W, and so's my wife! ― acl


@Spartacus, it was not fixable. ― rcollyer

check again; I just fixed it. :-p ― Spartacus

It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

comment Set of integers not divisible by smaller set of primes
@martin Although I haven't found anything faster than the code above there are memory optimization to be made especially when n is large relative to x, e.g. in the case where the result is {1}. I'll add these later today if I have time.

comment Set of integers not divisible by smaller set of primes
@martin Thanks for the Accept. I usually recommend waiting 24 hours first, to let everyone around the world have a chance to answer. However in this case I doubt there is a generally faster method available as this already makes use of highly optimized operations. Compilation to C could be faster still of course, but I don't do that. ;^)

I can't seem to reproduce this problem so I can't test a solution, but try putting Off[PacletInstall::offline] in your kernel/init.m file; it may load soon enough to have effect.

You should not normally need to use Remove. Based on your image I think it is being used proactively to prevent name collisions, but as you have discovered if there are no Global` Symbols you get a (harmless) error message. You should use ClearAll["Global`*"] instead.

Presumably you have a Remove["Global`*"] somewhere, but without more information this question cannot be answered so I am putting it on hold.
