[GAP Forum] Need help from users of Magma on Mac OSX

[Gordon Royle]

Dear GAP users

I do know that this is a GAP forum, but as I use both Magma and GAP, I hope someone else here does as well, and can spare me 30 seconds of their time.

For brevity, and omitting all background and explanation (which is included below), I just want to know what happens if you run the following code in Magma on your (Intel) Mac running any version of OSX.

for i in [1..25000] do
  g := TransitiveGroup(24,i);
end for;

My working hypothesis is that this code crashes with an “Interrupted System Call” if and only if the Mac is running OSX 11.1 or 11.2 (Big Sur).

I am seeking evidence regarding this hypothesis, ergo I need other people to try it on their systems, and collate the results.

If anyone willing to help can run this code, and then just send me (directly, not to the forum)


  *   Did it work (i.e. do nothing) or crash
  *   What version of OSX are you using

then I would be very grateful.

Thanks

Gordon

PS I have posted a more detailed version of this query on StackOverflow and apple.stackexchange, but there simply aren’t enough Magma users on those groups, and as far as I know there is no Magma forum.
