[seqfan] Mathematica and aspiring numbers

[Tanya Khovanova]

Hello SeqFans,

Something happened to my Mathematica. I can open a file and read it,
but I can't write into it or execute.

Does anyone know how to fix it?

If I would like to switch to free software, which one would you
recommend?

If you are in a mood for doing favors - you can help me. I urgently
need the next three aspiring numbers after 9997. (Aspiring numbers have
aliquot sequence ending in a perfect number)

Best, Tanya
