It's op. Maple represents objects using DAGs (directed acyclic graphs

I have just tested the following example re code in sage, and it fails
both on a Linux install and a Mac OS X install:
import re
p = re.compile('(a(b)c)d')
m = p.match('abcd')
m.group(0)

m.group(2)

I would still say that this is a bug, since the following does work:
sage: Permutation('(1)(2)(3)(4,5)')
[1, 2, 3, 5, 4]
and the docstring says the Permutation can be given a string in cycle
notation, and 1-cycles are usually omitted. Looking at the code

hi all,
I'm confused with the cycle notation for permutations (bug ?)
While the following works:
sage: Permutation( '(1,2)' )
the following yields an error:
sage: Permutation( '(4,5)' )

What's confusing is that if you go:

Jason, your tips on initializing the array and on counting the array

Daryl,
Do you have available the original install.log from your 3.0.1 and

during the GMP build.

There is no slowdown between sage-3.0.1 and 3.0.2 with the original
posted code, on sage.math:

So it looks like something processor-specific.

I was wondering about this myself. Maple has a command that does
exactly this (I think it is the "ops" command). Do you think SAGE should have
