how to get SHEEP MACSYMA

MKearny@gmail.com

Hello everyone,

I was wondering if anybody could tell me how to get SHEEP (it's a
symbolic tensor manipulation program, which runs under MACSYMA). All
the links I found (In particular, those on John Baez's site) don't
work.

Thanks!

You seem to be correct about the SHEEP links (the links at the CAIN and
SAL directories also seem to be broken), but these work:

Maple:

http://grtensor.phy.queensu.ca/ GRTensorII (freeware)

Mathematica:

http://www.math.washington.edu/~lee/Ricci/ (freeware)
http://smc.vnet.net/MathTensor.html (payware)

For SHEEP, see

http://arxiv.org/abs/gr-qc/0105094

Then try contacting Malcolm MacCallum

Good luck!

Try

ftp://ftphost.maths.qmul.ac.uk/pub/sheep

it is a standard lisp program.
